Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for supporting design of a column base so that a designer can easily grasp the entire result of a column base strength test performed at the time of designing a column base of a steel structure.
[0002]
[Prior art]
When designing the column base of a steel structure, after setting the column base type of each column base, various stress (axial force) for each load case (combination of vertical load and horizontal load) acting on the column base , Bending moment, shear force) and yield strength, and the degree of balance between stress and yield strength is tested to determine whether the column base model set at the initial stage of design is appropriate. . The strength test for such column base design is based on the value obtained by dividing the stress by the load strength (hereinafter referred to as the test value). If the test value exceeds 1, the stress exceeds the allowable strength. As a result, it is determined that a design change is necessary, and the proof stress is changed, that is, the column base type is changed. In the case of 1 or less, it may be preferable to make a design change although it is not determined that the design change is necessary, and the designer appropriately determines them.
[0003]
In recent years, a column base design support system has been developed in which such a column base strength test is performed using a computer. FIG. 19 is a flowchart showing the operation of the column base design support program used in the conventional column base design support system, particularly the screen transition. In the figure, solid line arrows indicate the flow of window transitions, and broken line arrows indicate the flow of data.
[0004]
In this column base design support system, first, the column base design support program is started and the main window is displayed, and the designer inputs the display of the strength test window on the main window to display the load test window. .
[0005]
FIG. 20 is a diagram showing a proof test window. The proof test window is a screen that displays the result of the proof test, and is a screen that is displayed based on the proof test table group 102 (see FIG. 19). In this strength test window, various load cases (combinations of vertical load and horizontal load) are used for each column axis direction (X direction, Y direction). Here, long-term L, earthquake E, short-term L + E, short-term LE , Final L + γE, final L−γE), that is, the result of determining whether the column base model set at the initial stage of design is appropriate based on the test result (test value) is displayed in a table format. It has become.
[0006]
The designer confirms the judgment result for each column base of the strength test target by the strength test window (corresponding to the test result sheet for each column base) configured in this way, and determines whether the design change is necessary. Then, if necessary, the model is changed (that is, the model is changed to a model having a different proof stress), the test value is calculated again, and the result of the re-determination based on the recalculated value is confirmed on the proof test window. This work is repeated, and the column base design is completed when the stress-proof balance becomes appropriate. The column / column base list window shown in FIG. 19 is configured based on the column / column base list table 101 for managing the column / column base information, and the column / column base information of all the column bases subject to the proof test. Is a screen for displaying a list.
[0007]
[Problems to be solved by the invention]
However, in the conventional column base design support system as described above, the verification result can be confirmed only for each column base by the strength verification sheet for each column base. It will take a considerable amount of time to check all of the legs that are subject to proof test. For this reason, the designer has only selected and confirmed several column bases that may have a problem in the degree of balance between stress and proof stress with reference to the design drawings based on the experience of many years.
[0008]
In this way, the conventional column base design support program does not give consideration to the display of the verification result so that the verification result of the entire column base subject to the proof test can be grasped in a short time. As described above, it is necessary to check one by one in the test result sheet (proof test window) as described above. As a result, the design takes a lot of time and takes a lot of time. Also, suppose that the stress-proof balance of a certain column base is biased to the extent that there is a margin in the yield strength (that is, it is set to a type of yield strength that has more margin than necessary for the stress acting on the column base). Even if it was possible to change to a model with a small proof stress, it was difficult to make a detailed grasp to confirm it because of time constraints, and economic design was extremely difficult.
[0009]
The present invention has been made in view of these points, and displays the entire arrangement of the column bases to be subjected to the proof test on the display means, and visually facilitates the degree of balance between the stress and the proof strength of the entire column base. Provides a column base design support method, a column base design support system, and a recording medium that records the column base design support program that can greatly reduce design time and facilitate the implementation of economic design. The purpose is to do.

When installed and provided by the FD 9a, it is installed in the hard disk 15 via the FD drive device 9.
[0025]
In the hard disk 15, a column / column base list table 16, a strength test table group 18, and a column / street symbol definition table 20 associated with each management ID are stored (see FIG. 2). The column / column base list table 16 and the strength test table group 18 are the same as the conventional column / column base list table 101 and the strength test table group 102, respectively. In the test table group 102, it is assumed that various types of information regarding each of the plurality of column bases subjected to the proof test are stored in advance. Note that the column base to be subjected to the proof test may be the entire column base of the building or a column base in an area arbitrarily selected by the designer. For example, an experienced designer can hit a column base that seems to have a problem with the balance between stress and proof stress from the design drawing, so that a desired region including the column base is selected. It will be.
[0026]
The tables of the column / column base list table 16 and the strength test table group 18 are not shown in the description of the prior art, but are shown here.
[0027]
FIG. 4 is a diagram showing a column / column base list table. The column / column base list table 16 includes a management ID and an X for identifying the column base for each of a plurality of column bases subject to the proof test (for convenience, only one column base is shown in FIG. 4). Code and Y code, column code (form that defines the combination of column material shape (square, circular, etc.), dimensions (diameter, plate thickness, etc.), material (strength, welding characteristics, etc.), and steel pipe symbol (A symbol representing the shape and dimensions of a steel pipe) and a column base type (a symbol representing a combination of the outer dimensions of the base plate, the bolt diameter of the anchor bolt, and the strength of each of the base plate and the anchor bolt) are stored.
[0028]
5 to 7 are diagrams showing each table constituting the yield strength test table group. FIG. 5 is a stress / proof stress information table, FIG. 6 is an axial force test table, and FIGS. 7 (a) and 7 (b) are columns. The column base test table for each axial direction ((a) is in the X-axis direction and (b) is in the Y-axis direction) is shown.
[0029]
The stress / proof stress information table shown in FIG. 5 includes a management ID and a column axis direction (X-axis direction) for each of a plurality of column bases to be tested for strength (only one column base is shown in FIG. 5 for convenience). , Y-axis direction) for each of the axial force, bending moment and shear force under various load conditions (long-term L, short-term L + S, short-term L + LW, short-term L + RW, short-term L + LE, short-term L + RE, ultimate L + γLE, ultimate L + γRE). Stress and proof stress are stored (for the axial force, only stress).
[0030]
In addition, in the axial force test table shown in FIG. 6, for each of a plurality of column bases subject to the strength test (only one column base is shown for convenience in FIG. 6), a management ID and a loading load (long-term, For each short-term, final), the compressive strength and tensile strength of the axial force are stored.
[0031]
Further, the column base verification table shown in FIG. 7 includes a management ID and a column axis direction (X-axis) for each of a plurality of column bases subjected to the strength test (only one column base is shown in FIG. 7 for convenience). For each axial force, bending moment, and shear force under various load conditions (long-term L, short-term L + S, short-term L + LW, short-term L + RW, short-term L + LE, short-term L + RE, final L + γLE, final L + γRE) And a determination flag based on the test value are stored.
[0032]
Here, the determination flag stored in the determination flag column 18a of FIG. 7 will be described. The judgment flag is for identifying the result of judging whether the balance between the proof stress and the stress related to the column base is appropriate based on the test value which is a value obtained by dividing the stress acting on the column base by the proof stress. Here, the value is any one of 0 to 5. The contents indicated by each value are as follows.
0 (OK): Within the allowable range for all stress types
1 (* 1): The axial force exceeds the concrete allowable compressive force at the bottom of the base plate.
2 (* 2): The axial force exceeds the allowable tensile stress of the anchor bolt
3 (* 3): Moment exceeds allowable capacity
4 (OK * 4): Within the shear load range of the anchor bolt
5 (* 5): Exceeds the shearing load of the anchor bolt
The characters in parentheses indicate the contents when the determination result is actually displayed on the display screen based on the determination flag.
[0033]
The above 1 to 5 when the test value exceeds 1 are tested in this order as to which of them corresponds, and the first corresponding one is stored as a determination result. That is, in the determination flag column 18a when the test value exceeds 1, the corresponding determination flag in the higher order of the test is stored.
[0034]
The operation of the column base setting support program according to the present embodiment will be described below with reference to FIGS.
Here, prior to the description of the flowchart of the column base design support program, an outline of the characteristic part in the column base design support program of the present embodiment will be described. Details will be described later. The column base design support program according to the present embodiment is a diagram schematically showing an arrangement of a plurality of column bases to be subjected to a proof test, as shown in FIG. (Referred to as a key plan) is displayed on the display means 3, and the column base marks representing the column bases on the key plan can be identified from the respective test results of the bending moment M and the shearing force Q applied to the column base. In addition, it is characterized in that it is visually distinguished and displayed by a mark, color tone, etc. according to the stage of the test value, and this key plan determines whether the balance between stress and proof stress is appropriate. This makes it possible for the designer to easily grasp visually and to shorten the time and efficiency of the design work.
[0035]
In the key plan, the position of the column base on the design drawing is replaced with the position of the coordinate system of the key plan, and the column base mark is displayed at the replaced position. For this reason, for example, even if the column arrangement on the actual design drawing is arranged at each intersection of each axis in FIG. 9A, the key plan is as shown in FIG. 9B. It is organized and expressed in the coordinate system of the key plan. Here, a case where the coordinate system of the key plan is an XY orthogonal coordinate system is illustrated.
[0036]
Now that the features of the present embodiment have been clarified, the operation of the column base design support program will be described with reference to FIGS.
When the CPU 19 recognizes that the column base design support program has been activated by a click operation of the mouse 5 by the designer, etc., it displays a main window on the display means 3 (S1). In the main window, various windows shown in FIG. 2 can be displayed by operating the mouse 5. Here, a display instruction of a proof test window indicating the proof test result is given by the designer, and when the CPU 19 recognizes this instruction, the proof test window is displayed on the display means 3.
[0037]
FIG. 10 is a diagram showing an example of a proof test window. This proof test window is a window configured based on the proof test table group 18 and has almost the same configuration as the conventional proof test window shown in FIG. 20, but the column base position definition field 21 is newly added. Different points are provided. The other parts except the column base position definition field 21 are the same, and the description thereof is omitted because it is redundant. Further, the column base position definition field 21 will be described in detail in the following corresponding portions. When the CPU 19 recognizes that the list button 23 of the strength test window has been clicked, it displays a column / street symbol definition window superimposed on the strength test window (S2).
[0038]
FIG. 11 is a diagram illustrating an example of a column / street symbol definition window.
Usually, on the design drawing, a symbol is attached to each column row to specify the column position. For example, in the example of FIG. 9A, R1 to R3, X1 to X3, and S1 to S4 correspond to the symbols. In the column / street symbol definition window, an input for defining such street symbols by the number of each coordinate axis in the coordinate system of the key plan (hereinafter referred to as coordinate axis street number) is performed (S3). In this way, by defining the street symbol by the number along the coordinate axis, a highly versatile design support system that can be applied to the proof test of a complicated column arrangement as shown in FIG. 9A is constructed. It will be possible. The symbols defined here are displayed on the respective coordinate axes displayed on the key plan.
[0039]
That is, in FIG. 11, the symbols X1 to X10 are input to the symbol input field 31 corresponding to the numbers 1 to 10 along the coordinate axis of the X axis, and the symbol input fields corresponding to the numbers 1 to 10 according to the coordinate axis of the Y axis. 32 shows a case where symbols Y1 to Y10 are input. In this case, the symbols are displayed on the key plan as shown in FIG.
[0040]
In addition, when inputting to the street symbol input fields 31 and 32, it may be directly input using the keyboard 7, or may be performed using the numbering setting support fields 33 to 35. Specifically, for example, when inputting X1 to X10 as shown in FIG. 11, first, an X axis radio button is selected in the axis selection field 36, and an initial is input in the numbering setting support field 33. By inputting X in the field 33a, 1 in the sequence number input field 33b, entering 1 and 10 in the sequence number start value setting field 33c and the sequence number start value setting field 34d, respectively, and pressing the numbering button 33e Thus, it is possible to automatically input X1 to X10 in the street symbol input field 31.
[0041]
Also, when it is desired to input the same number as the coordinate axis number, it is possible to input easily by using the numbering setting support field 34. That is, by inputting the number of the last cell to be set to the same value in the end cell input field 34a and pressing the numbering button 34b, the current cell where the cursor is positioned in the input field 31 is changed to the end cell input field 34a. The same value as the number along the coordinate axis is automatically input up to the input cell. The clear field 35 is for clearing all the contents entered in the cell entered in the cell designation field 35a from the current cell where the cursor is located by pressing the clear button 35b. Note that these numbering setting support functions are naturally provided by the column base design support program.
[0042]
When the street symbol is input to the street symbol input fields 31 and 32 and the OK button 37 is pressed by the designer (S4), the CPU 19 writes the definition information input here to the hard disk 15, and Close the street symbol definition window and return the control to the strength test window.
[0043]
As described above, the strength test window (see FIG. 10) is a column base position definition field 21 newly provided in the conventional strength test window shown in FIG. Each column base position is defined.
[0044]
More specifically, when the column base specified by X1 and Y1 on the design drawing is defined on the strength test window, as shown in FIG. 10, the X input field 21a of the column base position definition field and In the Y input field 21b, the coordinate axis number 1 corresponding to the symbols X1 and Y1 is entered to specify the column base position, respectively. Note that symbols are automatically displayed in the fields 22a and 22b next to the X input field 21a and the Y input field 21b, respectively. The column base position is defined with reference to the design drawing. The contents defined as described above are stored in the column / street symbol definition table 20 in the hard disk 15. FIG. 8 is a diagram showing a column / street symbol definition table. As shown in FIG. 8, in the column / street symbol definition table 20, the above definition contents are managed for each management ID.
[0045]
This column base position definition input is performed for all the column bases subject to the proof test (S5). After that, when the designer performs a key plan creation instruction operation by operating the mouse 5 or the like (S6), the CPU 19 A key plan is generated based on the proof stress test table group 18 and the column / street symbol definition table 20 and displayed on the display means 3 (S7).
[0046]
12 to 16 are diagrams showing an example of the key plan. FIG. 12 shows the entire key plan, and FIGS. 13 to 16 show the key plan actually displayed on the display means 3. The key plan has been briefly described so far, but will be described in detail here.
In the key plan (see FIG. 12), coordinate axes based on a two-dimensional coordinate system (here, the X axis and the Y axis based on an orthogonal coordinate system) are displayed at predetermined intervals, and each axis has a column / street symbol definition window ( As shown in FIG. 11, symbols are sequentially displayed in the X-axis direction (right direction in the figure) and the Y-axis direction (upward direction in the figure). For all the column bases defined using the strength test window (see FIG. 10), the column base marks □ are displayed at the intersections of the respective column base positions, that is, the coordinates specified by the street symbols. In the upper right of the mark □, stress information about the column base is displayed in a table format.
[0047]
The column base mark □ displayed on the key plan is visually distinguished according to the display color according to the stage of the column base test result corresponding to the display position. In this display, processing performed by the CPU 19 is as follows.
The CPU 19 determines, for each column base, a plurality of test values for each stress of the bending moment M and shear force Q for each column base from the column base verification table (see FIG. 7) of the yield strength test table group 18. The maximum value is searched, and the display color of the stage to which each maximum value belongs is displayed with the column base mark □ in the corresponding display color based on the color definition table shown in FIG. Is displayed in the corresponding part of the upper right table (in the upper and lower cells on the lower left side of the table). This table will be described in detail later.
[0048]
Here, the column base mark □ indicates the bending moment M within □ and the shearing force Q indicates the frame, and the column base mark □ is filled with the display color of the maximum test value of the bending moment M, and the column base mark □ The color of the frame is displayed in the display color of the maximum test value of shear force Q. Specifically, in FIG. 13, the column base 41 of coordinates X1 and Y1 has a maximum value of 0.56 among the test values of the bending moment M, and is greater than 0.5 and equal to or less than 0.75. Since the maximum value of the test value of Q is 0.97 and exceeds 0.75 and is 1.0 or less, the column base mark □ is filled with light blue according to the color definition in reference numeral 51 in FIG. The column base mark □ frame is displayed with a yellow line. In addition, each reference value (0.5, 0.75) which classifies a test value in FIG. 17 can be changed arbitrarily.
[0049]
Further, the CPU 19 sets the maximum value of the bending moment M for each of the same column base model among a plurality of test values managed in the column base test table (see FIG. 7) of the yield test table group 18. And the maximum value of the shearing force Q, respectively, and for the corresponding column base, the color definition of reference numeral 52 in FIG. 17 is applied with priority. That is, since the maximum test value of the bending moment M is 1.28, the column base 42 in FIG. 14 is displayed in pink within the column base mark □ frame according to the color definition of reference numeral 51 in FIG. Since the model is “□ -500-8M-42”, this corresponds to the column base having the maximum test value of the bending moment M, and therefore the inside of the column base mark “□” is displayed in dark pink. Further, the column base 43 shown in FIG. 15 has a maximum value of both the bending moment M and the shearing force Q among the types of “□ -500-8M-48”. The color definition of the reference numeral 52 is applied to both the column base mark □ frame and is displayed in dark pink and red bold lines, respectively.
[0050]
Next, the output contents of the table displayed at the upper right of the column base mark □ will be described. FIG. 18 is an explanatory diagram of output contents. When the table is displayed, the display process performed by the CPU 19 is as follows.
For each column base, the CPU 19 extracts the column code, the column base type, and the determination result from the yield test information table, and the maximum test values of the bending moment M and the shear force Q searched previously, The load case that yielded the maximum test value and the determination result are extracted and displayed in a table format on the upper right of the corresponding column base mark. In addition, about the test value exceeding 1, since design change is required, the information which can be identified is displayed. Specifically, the column base 44 of FIG. 16 has a maximum bending moment M exceeding 1, and the contents (* 3) are displayed in the table. Note that the output content table and the color definition table of FIG. 17 are also displayed on the key plan on the display means 3 as shown in FIG. 13 so that the designer can easily confirm.
[0051]
The designer can visually grasp the stress-proof strength balance of the entire column base subject to the strength test from the key plan configured as described above. In order to check whether there is a column base that needs to be changed, it is displayed on the key plan with a display color indicating that the test value exceeds 1, and a display color indicating that it is the maximum among the same model When a column base that requires a design change (for example, the column base 44 in FIG. 16) is found, the column base mark to be changed is selected in order to change the column base type. Click to display the proof test sheet (proof test window) of the column base on the display means 3. Then, referring to the judgment result of the output contents table, select an appropriate column base model from the current materials etc. based on the current stress-proof balance, and input it to the column base type input field 24 on the yield test window. Press the calculation ON button 25.
[0052]
When the calculation ON button 25 is input, the CPU 19 recalculates the test values for all the column bases on the key plan based on the changed column base model, and updates the hard disk strength test table. Then, the designer gives an instruction to display the key plan again in order to confirm the determination result after changing the column base model. When this instruction is given, the CPU 19 makes a key based on the strength information table updated with the recalculation data. View the plan. The designer confirms the displayed key plan and repeats the same processing as described above if further changes are required.
[0053]
Further, the column base 45 in FIG. 14 is white in the column base mark □ and the frame of the column base □ is indicated by a black thin line. This implies that in this column base model (□ -500-8S-42), each of the bending moment and shear strength against stress is larger than necessary and can be changed to a smaller strength. Yes. Thus, since the degree of balance between stress and proof stress can be easily grasped visually by the column base mark, a fine economic design becomes possible.
[0054]
As described above, key plan confirmation and column base type change are repeated, and the column base design is completed when a good balance between stress and proof stress is obtained (S8).
[0055]
10 to 13 show a case where the omnidirectional display tab 61 is selected and a key plan based on the test results for both the X and Y column axis directions is displayed. It is also possible to switch to the key plan display when the tab 62 or the Y direction display tab 63 is selected and the column axis direction is limited to one direction. At this time, the CPU 19 receives an input from the designer, recognizes which tab is selected, obtains a strength test result for the recognized tab direction from the strength test table, generates a key plan, and displays the display means 3. Perform the process of displaying above.
[0056]
In addition, the key plan shown in FIGS. 12 to 16 is a key plan based on the test results for the column axis directions in both the X and Y directions as described above, and simultaneously displays both the bending moment and the shearing force. It is a combination of long-term load, short-term load, and ultimate load consisting of a combination of horizontal load based on column axis direction, stress type (bending moment, shear force), vertical load and horizontal force direction (right, left). It is also possible to limit the display.
[0057]
When the column base design is completed as described above, a print window is displayed by the designer's mouse 5 operation, and when a print instruction is input on the print window (S9), the CPU 19 is displayed on the key plan window. The key plan being printed is printed by a printer and output (S10). The printed key plan corresponds to the key plan shown in FIG.
[0058]
When the CPU 19 recognizes that the display instruction of the column / column base list window has been made by clicking the mouse 5 on the main window, etc., the CPU 19 displays a column / column base list window (not shown). This column / column base list window is a window generated based on the column / column base list information table, and is a screen for displaying a list of column / column base information of all the column bases subjected to the strength test.
[0059]
As described above, according to the present embodiment, the key plan schematically showing the arrangement of the column bases to be subjected to the proof test is displayed on the display unit 3, and the column base marks on the display unit 3 are displayed. , The bending moment and shear force are visually distinguished according to the stage of the test results, and the test results can be visually identified from each column base mark.
