Description

  The present invention relates to a technique for performing a simple seismic diagnosis.

  There have been various earthquake-resistant diagnostic methods for buildings. For example, Japanese Patent Application Laid-Open No. 2004-162399 discloses a technique for performing an earthquake-resistant diagnosis in a short time without special expertise. Specifically, it is classified into the diagnosis items of the five evaluation elements of the ground, foundation, building main structure, building secondary member, and workpiece, and each of the five evaluation elements is further classified into the middle diagnosis items.

  In the above-described prior art, an attempt has been made to make it possible to perform a seismic diagnosis of a building as easily as possible, but the problem caused by the simple seismic diagnosis is not considered. That is, although it is clear that the accuracy of the calculated index value decreases if it is simplified, no information about the accuracy can be presented to the user.

  Accordingly, an object of the present invention is to provide a simple seismic diagnosis technique that can assist an objective judgment of a user.

  The simple earthquake-resistant diagnosis processing method according to the present invention calculates a first parameter from a floor area and a wall length of an evaluation floor or more by a processing device, and stores the first parameter in a storage device, and a processing device, A shape index value specifying step for specifying a shape index value from an index value related to formability, an index value related to a side length ratio, an index value related to a basement, and an index value related to plane rigidity and stored in the storage device, Calculating an upper limit value and a lower limit value of the second parameter from the first parameter stored in the above and at least a predetermined upper limit value function and a lower limit value function, and storing them in a storage device; The upper limit value and the lower limit value of the structural seismic index are calculated from the index value related to aging and the shape index value stored in the storage device and the upper limit value and lower limit value of the second parameter, And a structural seismic index calculation step of storing the 憶 device.

  Thus, the data of the range of the upper limit value and the lower limit value can be used for the structural seismic index. By presenting these upper and lower limits to the user, the user is able to use the possible range of structural seismic indices, ie, accuracy data, compared to the case where only one value is shown. This makes it possible to judge the results of seismic diagnosis more objectively.

  In the first parameter calculation step described above, the first parameter may be calculated by dividing the wall length by the floor area.

  Furthermore, in the shape index value specifying step described above, a table in which shape index values are registered in correspondence with index values related to shapeability, index values related to side length ratios, index values related to basements, and index values related to plane stiffness A shape index value may be specified by searching.

  Furthermore, the upper limit function and the lower limit function may be exponential functions. Note that the upper limit value function and the lower limit value function are, for example, functions obtained recursively from actual examples.

  Further, in the structural earthquake resistance index calculation step described above, the processing device calculates the product of the index value related to aging, the shape index value, and the upper limit value of the second parameter as the upper limit value of the structural earthquake resistance index, and stores it in the storage device. A step of storing, and a step of calculating a product of an index value related to aging, a shape index value, and a lower limit value of the second parameter as a lower limit value of the structural seismic index by the processing device, and storing the calculated value in a storage device. Good.

  Further, the processing device may further include a step of comparing the upper limit value and lower limit value of the structural earthquake resistance index value with a predetermined threshold value and determining the necessity of detailed earthquake resistance diagnosis. For example, if the upper limit value and the lower limit value are above the threshold value, it is determined that there is no need for detailed seismic diagnosis. Further, if the range exceeding the threshold value within the range of the upper limit value and the lower limit value is equal to or greater than a predetermined ratio, it may be determined that there is no need for detailed seismic diagnosis.

  In addition, the wall length described above may include a wall length in the first direction and a wall length in the second direction of the building subject to simple seismic diagnosis. This makes it possible to determine in which direction the earthquake strengthening is necessary. In addition, the index regarding the plane rigidity may include a value for each of the first and second directions.

  Further, the processing device may further include a determination step of determining whether the building subject to simple earthquake-resistant diagnosis satisfies the condition regarding the building confirmation time and the structure type of the building has a predetermined structure. In this case, when it is determined in the determination step that the building for the simple earthquake-resistant diagnosis satisfies the conditions regarding the building confirmation time and the structure type of the building has a predetermined structure, the steps after the first parameter calculation step Steps may be executed. Thus, when a certain level of seismic strength is ensured, the simple seismic diagnosis process described above is omitted.

  It is also possible to create a program for causing a computer to execute the method according to the present invention. The program is, for example, a storage medium or a storage device such as a flexible disk, a CD-ROM, a magneto-optical disk, a semiconductor memory, and a hard disk. Stored in In some cases, digital signals are distributed over a network. Note that data being processed is temporarily stored in a storage device such as a computer memory.

  ADVANTAGE OF THE INVENTION According to this invention, in the simple earthquake-resistant diagnosis of a building, a user's objective judgment comes to be accelerated | stimulated.

  FIG. 1 shows a functional block diagram of a simple seismic diagnosis apparatus 100 according to an embodiment of the present invention. The simple seismic diagnosis apparatus 100 includes a diagnostic eligibility determination processing unit 40, a wall length input unit 1, an area input unit 3, an aging index input unit 5, a wall length storage unit 7, an area storage unit 9, and an aging Index storage unit 11, L / S calculation unit 13, L / S storage unit 15, shape index calculation index input unit 17, shape index calculation index storage unit 19, owned performance basic index calculation unit 21, and possession A basic performance index storage unit 23, a shape index calculation unit 25, a shape index storage unit 27, a shape index calculation table 29, a structural earthquake resistance index calculation unit 31, a structural earthquake resistance index storage unit 33, and a determination processing unit 35 And an output unit 37.

  The diagnosis eligibility determination processing unit 40 receives an input from the user and determines whether or not a building to be subjected to the simple earthquake-resistant diagnosis is a diagnosis target. In addition, when it is determined that it is a diagnosis target, the wall length input unit 1, the area input unit 3, the aging index input unit 5, and the shape index calculation index input unit 17 are instructed to perform processing, and the diagnosis target If it is determined that it will not occur, the output unit 37 outputs that effect.

The wall length input unit 1 receives an input about the wall length from the user and stores it in the wall length storage unit 7. The area input unit 3 receives an input about the floor area from the user and stores it in the area storage unit 9. The aging index input unit 5 receives an input about the aging index and stores it in the aging index storage unit 11. The L / S calculation unit 13 reads the wall length L from the wall length storage unit 7 and the floor area S from the area storage unit 9, calculates L / S, and stores the calculation result in the L / S storage unit 15. The retained performance basic index calculation unit 21 reads data from the L / S storage unit 15, calculates the retained performance basic index E ₀ according to a preset function, and stores it in the retained performance basic index storage unit 23.

  The shape index calculation index input unit 17 receives an input about an index for calculating the shape index from the user and stores it in the shape index calculation index storage unit 19. The shape index calculation unit 25 reads the data stored in the shape index calculation index storage unit 19 and the data stored in the shape index calculation table 29, identifies the shape index SD, and stores it in the shape index storage unit 27.

  The structural seismic index calculation unit 31 reads the data stored in the secular index storage unit 11, the retained performance basic index storage unit 23, and the shape index storage unit 27, calculates the structural seismic index, and stores it in the structural seismic index storage unit 33. Store. The determination processing unit 35 reads the data stored in the structural earthquake resistance index storage unit 33 and makes a determination as to the necessity of comparison processing with a predetermined threshold and detailed earthquake resistance diagnosis. The output unit 37 outputs the output of the determination processing unit 35 and the data stored in another storage unit to an output device such as a display device or a printer.

  Next, processing of the simple seismic diagnosis apparatus 100 will be described with reference to FIGS. First, the diagnostic eligibility determination processing unit 40 performs diagnostic eligibility determination processing (step S1). This process will be described with reference to FIG. The diagnostic eligibility determination processing unit 40 urges the user to input the building confirmation date or completion date, accepts the input of the building confirmation date or completion year from the user, and stores it in a storage device such as a main memory. Store (step S21). It asks for the date of construction confirmation as much as possible, but if the date of construction confirmation is unknown, it asks for the completion year instead. Then, it is confirmed whether the input data is a building confirmation date or a completion year (step S23).

  If it is determined that the building confirmation date is entered, it is confirmed whether the building confirmation date is after a specific date (specifically, June 1, 1981). Step S29). On June 1, 1981, the new seismic design method was enforced, and after that, building confirmations were judged to be buildings with seismic strength sufficient to avoid the need for simple seismic diagnosis. . Therefore, when it is determined that the building confirmation date is after June 1, 1981, the diagnosis unnecessary is set (step S27). Then, the process returns to the original process. On the other hand, if it is determined that the building confirmation date is before June 1, 1981, the process proceeds to step S31.

  On the other hand, if it is determined that the completion year is entered instead of the building confirmation date, it is determined whether the completion year is a specific year (specifically, 1984) or later (step S25). This is because if the date of construction confirmation cannot be specified, it cannot be determined accurately, but if the completion date is after 1984, it is assumed that the date of construction confirmation is also after June 1, 1981. If it is determined that the completion year is after 1984, the process proceeds to step S27. On the other hand, if it is determined that the completion year is before 1984, the process proceeds to step S31.

  When it is determined that the building confirmation date is before June 1, 1981, or when the completion date is determined to be before 1984, the user is requested to enter the structure map. The user's input about the presence / absence of the structure diagram is accepted from the user (step S31). Then, it is determined whether or not an input “with structure diagram” has been made (step S33). If it is determined that the input “with structure diagram” has been made, the user is prompted to input the structure type, the structure type input is received from the user, and stored in a storage device such as a main memory (step S35). . Then, it is determined whether the structure type is RC structure (step S37). If it is determined that the building is RC-built, the building is qualified because it is qualified for the following diagnosis (step S39). Then, the process returns to the original process.

  On the other hand, if the structure type is not RC construction, it is determined whether it is SRC construction (step S41). If it is determined that the structure is SRC, the user is prompted to input the steel frame, receives the steel frame input from the user, and stores it in a storage device such as a main memory (step S43). And it is judged whether a steel frame form is a non-full stomach type (step S45). When it is determined that the steel frame type is unfilled, the process proceeds to step S39, where it is considered as an RC structure, and the qualification is set as qualifying for the diagnosis performed below. On the other hand, if it is determined that the steel frame format is other than the non-full stomach type, it is ineligible for diagnosis, and thus ineligibility is set (step S47).

  If it is not SRC structure in step S41 and the structure type is unknown, the user is prompted to enter the floor number or span length, the floor number or span length input by the user is accepted, and the storage device such as the main memory is received. Store (step S49). Then, it is determined whether a predetermined condition that the floor number is 7 floors or more or the maximum span length is 9 m or more is satisfied (step S51). If it is determined that the predetermined number of floors is 7 floors or more or the maximum span length is 9 meters or more, the SRC construction is assumed and the process proceeds to step S47. In other words, it is determined that the building is ineligible for the following diagnosis. On the other hand, if the predetermined condition that the number of floors is 7 or more or the maximum span length is 9 m or more is not satisfied, the user is prompted to input the inner and outer walls, and the user's inner and outer walls are input. Is stored in a storage device such as a main memory (step S53). Then, it is determined for the user whether the main inner / outer wall is a predetermined structure such as a concrete structure or a dry structure (step S55). If it is determined that the inner and outer walls are of a predetermined structure such as concrete or dry, the building is qualified as being eligible for the following diagnosis. On the other hand, in the case of other construction or inability to confirm, the building is set as ineligible as being ineligible for the following diagnosis.

  If it is determined in step S33 that there is no structural drawing, the user is prompted to input the presence / absence of a design drawing, and the input of the presence / absence of the design drawing is accepted from the user (step S57). Then, it is determined whether there is a design drawing (step S59). If it is determined that there is a design drawing, the process proceeds to step S49. On the other hand, if it is determined that there is no design drawing, the determination cannot be made, and the process proceeds to step S47 via the terminal C.

  By performing such processing, diagnostic preprocessing is performed.

  Returning to the description of FIG. 2, the diagnostic eligibility determination processing unit 40 determines whether eligibility is set in step S1 (step S3). If it is determined that ineligibility or diagnosis unnecessary is set, the diagnosis qualification determination processing unit 40 instructs the output unit 37 to output a message indicating that the diagnosis is inappropriate or unnecessary, and outputs the message. The unit 37 displays a message unsuitable for diagnosis or not necessary for diagnosis on the display device (step S19). Then, the process ends.

  On the other hand, if it is determined that the qualification is set, the qualification determination processing unit 40 sends the wall length input unit 1, the area input unit 3, the aged index input unit 5, and the shape index calculation index input unit 17. An instruction is output to start processing.

Therefore, for example, the display as shown in FIG. 4 is performed to prompt the user to input and confirm. In FIG. 4, each stage in diagnosis is presented. In stage 1, the user is prompted to set the evaluation floor and measure the wall length. In stage 2, the user is prompted. The user is prompted to input the wall length L and the floor area S equal to or greater than the evaluation floor, presents the calculation result of L / S, and presents the calculation result of the retained performance basic index E ₀ . In step 3, the user is prompted to input the secular index T, and in step 4, the user is prompted to input the shaping index Gi_a, the side length ratio index Gi_b, the basement index Gi_c, and the plane stiffness index Gi_d. Urging. As described above, in the present embodiment, the intermediate progress of the calculation is also presented to the user.

  First, the user needs to set the evaluation floor and measure the wall length L and the floor area S equal to or higher than the evaluation floor according to the structure diagram or the design drawing. As a general rule, the evaluation floor is the first floor. However, if the first floor is different from the standard floor plan, and the standard floor is judged to have an extremely small amount of walls, the lowest floor of the standard floors is set as the evaluation floor. Further, as shown in FIG. 5, the wall length is measured separately in the column grid direction (X, Y) of the evaluation floor. In the example of FIG. 5, the length in the X direction is three columns, and the length in the Y direction is five columns. As a general rule, the wall whose length is to be measured is reinforced concrete. However, if there is no structural diagram and it is unavoidable, the main inner / outer wall structure is roughly confirmed, and the walls that are judged to be RC structures are targeted. Further, as shown in FIGS. 6 (a) to 6 (d), only the length of the wall having both sides or one side attached to the column is measured. At that time, as shown in FIG. 6 (e), only the portion where the wall length excluding the column width is continuously 45 cm or more is included as the wall length.

  Thus, the user measures the wall length L and the floor area S equal to or higher than the evaluation floor according to the structure diagram or the design drawing.

As shown in FIG. 4, the wall length input unit 1 and the area input unit 3 prompt the user to input the wall length L and the floor area S equal to or higher than the evaluation floor in each of the XY directions. The wall length L is stored in the wall length storage unit 7 and the floor area S is stored in the area storage unit 9 (step S5). As shown in FIG. 4, on the display screen, a table 201 for inputting the wall length L in each of the XY directions and the floor area S equal to or higher than the evaluation floor is presented, and input is made in a frame surrounded by a bold line 202. Prompt. The floor area S is input for each of X and Y for convenience, but the same value may be input. In the example of FIG. 4, the wall length L in the X direction is 60 m, the wall length L in the Y direction is 80 m, and the floor area S is 3000 m ² .

  Usually, the wall area is used instead of the wall length in seismic diagnosis, but the wall length S is used here because it may be difficult to measure the wall thickness when there is no structural drawing. .

  Next, the L / S calculation unit 13 reads data from the wall length storage unit 7 and the area storage unit 9, calculates the wall length L / floor area S, and stores it in the L / S storage unit 15 (step S6). ). In the present embodiment, L / S calculation results are displayed in the X direction and the Y direction in the table 201 of FIG. In the example of FIG. 4, the value of L / S is 0.02 in the X direction and 0.027 in the Y direction.

Furthermore, the possessed performance basic index calculating unit 21 calculates the retained performance basic index E ₀ using the data stored in the L / S storage unit 15 and stores it in the retained performance basic index storage unit 23 (step S7). . The inventor of the present application has unambiguously specified that the relationship between L / S and the retained performance basic index E ₀ is as shown in FIG. 7 from many past standard cases. In other words, the example shows a very wide distribution, but can basically be expressed in the form of an exponential function E ₀ = ax ^b (x is a variable and inputs the value of L / S). Therefore, if the upper limit value and the lower limit value are not specified, the reliability of the value is lowered. Thus, in this embodiment, by preparing the upper limit function E _0max = a _max x ^bmax represented by the curve p, a lower limit value represented by the curve r function ^{_{E 0min = a min x bmin,}} X calculating the upper limit value E _0max and the lower limit value E _0min both for holdings performance basic indicator of the L / S of the L / S and Y-direction in the direction. The upper limit function and the lower limit function are also obtained by regression calculation. Incidentally, it is prepared also the ^_E 0rec = a _rec x brec represented by the curve q as a regression equation of the total cases, may be calculated also for this value. Note that a _max = 1.15, a _min = 0.57, and a _rec = 0.57. In FIG. 7, the corresponding range of E ₀ is indicated by a dotted rectangle.

In the example of FIG. 4, the table 203 representing the range of E _0, the upper limit value, the overall regression equation for each lower limit, the X-direction of E _0, E ₀ in the Y direction is presented.

  In addition, since it is not easy to determine the presence of a very short column from a three-dimensional view because it has a sleeve wall, a vertical wall, and a waist wall, the evaluation of the very short column is not performed.

  Returning to the description of FIG. 2, the aging index input unit 5 prompts the user to input the aging index T, receives the input of the aging index T from the user, and stores it in the aging index storage unit 11 (step S8). ). In the example of FIG. 4, the calculation standard table 204 of the aging index T is presented to the user, and the user specifies the value of the aging index T from the building age and specifies the aging index specified in the input field 205. Enter a value for T. In addition, the calculation standard table 204 is the number of years of construction in the calculation table of the secular index T used for the first diagnosis method in the Japan Building Disaster Prevention Association “2001 revised edition seismic diagnosis standard for existing reinforced concrete structures same commentary”. It corresponds to the part.

  Next, the shape index calculation index input unit 17 prompts the user to input the shapeability index Gi_a, the side length ratio index Gi_b, the basement index Gi_c, and the plane stiffness index Gi_d, accepts the input from the user, Are stored in the shape index calculation index input unit 19 (step S9).

  The formability index Gi_a is determined by the planar shape of the building. For example, if the rectangle is as shown in FIG. 8A or almost rectangular, it is 1.0, and if it is other than the rectangle shown in FIG. 8B, it is 0.8. To do. Further, the side length ratio index Gi_b is determined by the narrowness (side length ratio) of the planar shape of the building. For example, when the long side length is 40 and the short side length is 10 as shown in FIG. 9A, the long side / short side = 4 is the side length ratio. On the other hand, when the long side length 63 and the short side length 7 are as shown in FIG. 9B, the long side / short side = 9 is the side length ratio. In the present embodiment, the side length ratio index Gi_b is 0.8 when the side length ratio exceeds 8, and is 1.0 when the side length ratio is 8 or less. That is, Gi_b = 1.0 in the case of FIG. 9A, and Gi_c = 0.8 in the case of FIG. 9B.

  The basement index Gi_c is determined based on whether there is a basement in the building. In the present embodiment, 1.0 is set when there is a basement, and 0.8 when there is no basement. The plane stiffness index Gi_d is determined in the X and Y directions based on the deviation of the planar arrangement of both side or one side pillared walls. For example, Gi_d = 1.0 when there is no bias as shown in FIG. 10 (a), and Gi_d = 0.9 when there is a slight bias as shown in FIG. 10 (b). In such a case, Gi_d = 0.8.

  In the example of FIG. 4, the calculation criterion table 206 of the shaping index Gi_a is presented to the user. The user specifies the value of the shaping index Gi_a from a plan view or the like, and enters the input field 207. To enter. Further, a calculation reference table 208 for the edge length ratio index Gi_b is presented to the user, and the user specifies the value of the edge length ratio index Gi_b from a plan view and the like and inputs it in the input field 209. A calculation standard table 210 for the basement index Gi_c is presented to the user, and the user specifies the value of the basement index Gi_c from the presence or absence of the basement and inputs it in the input field 211. Further, a calculation criterion table 212 for the plane stiffness index Gi_d is presented to the user. The user specifies the value of the plane stiffness index Gi_d in the X direction and the Y direction from a plan view or the like, and an input field 213. To enter.

  Returning to the description of the processing in FIG. 2, the shape index calculation unit 25 uses the data (Gi_a, Gi_b, Gi_c, Gi_d) stored in the shape index calculation index storage unit 19 and the shape index calculation table 29 to calculate the shape. The index SD is specified and stored in the shape index storage unit 27 (step S11). The shape index calculation table 29 is a table as shown in FIG. 11, for example. The example of FIG. 11 includes a column of the formability index, a column of the side length ratio index, a column of the basement index, a column of the plane stiffness index, and a column of the corresponding shape index SD. From this table, the value of the row shape index SD identified from the shaping index, the edge length ratio index, the basement index, and the plane stiffness index is identified.

  In addition, the shape index SD in this embodiment is the calculation of the shape index SD used for the second diagnosis method in the Japan Building Disaster Prevention Association “2001 revised edition: Seismic diagnostic criteria for existing reinforced concrete structures same explanation”. Among the items, “formability”, “side length ratio”, “presence / absence of basement”, and “plane rigidity” are almost performed. In addition, the necking, expansion joint, blow-through, uniformity of layer height, presence / absence of piloti, and (rigid / heavy) ratio of the upper and lower layers, which are prescribed in the secondary diagnostic method, are not considered.

  As a continuation of FIG. 4, the output unit 37 presents a display as shown in FIG. That is, in stage 5, the calculation result of the shape index SD is presented, and in stage 6, the calculation result of the structural earthquake resistance index Is and a graph representing the relationship between L / S and Is are presented.

  In FIG. 12, the shape index SD calculation table 220 shows the input Gi_a, Gi_b, Gi_c, and Gi_d values and the shape index SD values identified from them. Since Gi_d has different values in the X and Y directions, Gi_a, Gi_b, and Gi_c have the same values in the X and Y directions, and the values in the X and Y directions are calculated for the shape index SD.

  Returning to the description of the processing in FIG. 2, the structural seismic index calculation unit 31 reads the data stored in the aging index storage unit 11, the retained performance basic index storage unit 23, and the shape index storage unit 27, and obtains the structural seismic index. Calculate and store in the structural seismic index storage unit 33 (step S13). Calculated according to the secondary diagnostic method described above.

For E ₀ , a minimum upper limit value and a lower limit value are calculated, and there are X and Y directions at the same time. Therefore, at least four structural seismic index values are calculated.

In the example of FIG. 12, the calculation process of the structural seismic index Is is shown in the structural seismic index calculation table 230 presented to the user in Step 6. That is, L / S, E ₀ classification, E ₀ , SD, T, and Is are presented. As described above, Is is calculated separately in the X direction and the Y direction. In the example of FIG. 12, not only the upper limit value and the lower limit value but also regression values are presented for E ₀ , and the corresponding structural seismic index is also shown. Calculated and presented.

  In addition, when processing is performed so far, the output unit 37 can present the graph shown in the lower stage of stage 6 in FIG. In the graph 240, the vertical axis represents Is, and the horizontal axis represents L / S. The rhombus plot shows the existing data, and the straight line with Is = 0.6 represents the threshold value (determination value) of the structural seismic index. Further, a thick line 240a at L / S = 0.02 represents a range of Is values in the X direction (upper limit value to lower limit value), and a thick dotted line 240b represents a range of Is values in the Y direction (upper limit value to lower limit value). Represents.
