Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for supporting the design of a column pedestal by allowing a designer to easily grasp the results of a column base proof test performed when designing a column pedestal of a steel structure.

[0002]

2. Description of the Related Art When designing a column base of a steel structure, a column base model of each column base is set, and then each of various load cases (combination of vertical load and horizontal load) acting on the column base is set. Calculate various stresses (axial force, bending moment, shear force) and proof stress, test the degree of balance between stress and proof stress,
A determination is made as to whether or not the column base type set at the initial stage of design is appropriate. The strength test related to such column base design is performed based on a value obtained by dividing the stress by the strength (hereinafter referred to as a test value). When the test value exceeds 1, the stress exceeds the allowable strength. That is, it is determined that a design change is necessary, and a change in the strength, that is, a change in the column base type is performed. When the number is 1 or less, it is not determined that a design change is necessary, but it may be preferable to make a design change in some cases, and the designer appropriately determines these.

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 arrows indicate the flow of window transition, and broken arrows indicate
The data flow is shown.

In this column base design support system, first, a column base design support program is activated to display a main window, and on the main window, a designer inputs a display instruction of a strength test window to open a strength test window. Is displayed.

FIG. 20 is a diagram showing a proof stress window. The proof test window is a screen for displaying the result of the proof test, and is a screen displayed based on the proof test table group 102 (see FIG. 19). In the strength test window, various types of load cases (a combination of a vertical load and a horizontal load) are used for each column axis direction (X direction, Y direction). In this case, long-term L, earthquake E, short-term L + E, short-term L−
E, final L + γE, final L−γE), that is, the results of determining whether or not the column type set at the initial design stage based on the test results (test values) are appropriate are displayed in a table format. It has become.

[0006] The designer confirms the judgment result of each pedestal to be subjected to the proof test by the proof test window (corresponding to the test result sheet for each pedestal) configured as described above.
The result of judging whether a design change is necessary, changing the model if necessary (that is, changing to a model with a different proof stress), causing the test value to be calculated again, and re-determining based on the recalculated value. Is confirmed on the proof stress window. This work is repeated, and when the stress-proof strength balance becomes appropriate, the column base design is completed. The column / column base list window shown in FIG. 19 is configured based on the column / column base list table 101 for managing column / column base information, and includes column / column base information of all column bases subjected to the strength test. Is a screen displaying a list.

[0007]

However, in the conventional column base design support system as described above, the verification result can be checked only for each column base using the strength test sheet for each column base. Therefore, it takes a considerable amount of time to confirm all of the column bases for which the strength is to be tested, among the column bases of the structure. For this reason, the designer
With reference to the design drawings, only some column bases having a problem in the degree of balance between stress and proof stress were selected and confirmed based on feelings based on many years of experience.

As described above, in the conventional column pedestal design support program, no consideration has been given to displaying the test results so that the test results of the entire column pedestal to be subjected to the strength test can be grasped in a short time. As described above with reference to the design drawings, it is necessary to check each test result sheet (proof strength test window) one by one, and as a result, it takes a lot of time and much time to design. Also, if the stress-proof strength balance of a certain column base is biased in a state where there is a margin in the strength (that is, the type is set to a strength model that has an extra margin for the stress acting on the column base). However, even if it is possible to change to a model with a small proof stress, it is difficult to grasp the details in a time-sensitive manner, and it is extremely difficult to design economically.

The present invention has been made in view of the above points, and displays the arrangement of the entire pedestal to be subjected to the proof test on a display means, and visually confirms the degree of balance between the stress and the proof stress of the entire pedestal. -Base design support method, column-base design support system, and record that records a column-base design support program that enables the design time to be significantly reduced and the economical design to be easily implemented by making it easy to grasp The purpose is to provide a medium.

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. Test table group 10
It is assumed that various information regarding each of the plurality of pedestals to be subjected to the strength test is stored in advance in 2. Note that the column pedestal to be subjected to the strength test may be the entire column pedestal of the building, or may be a column pedestal in an area arbitrarily selected by the designer. For example, an experienced designer can hit a column base that is likely to have a problem with the balance between stress and proof stress from the design drawing, so that a desired area including the column base is selected. Will be.

Each of the column / column base list table 16 and the strength test table group 18 is not shown in the description of the prior art, but will be shown here.

FIG. 4 is a view showing a column / column base list table. The column / column pedestal list table 16 contains a plurality of column pedestals to be subjected to a strength test (for convenience, FIG.

The operation of the pedestal setting support program according to this embodiment will be described below with reference to FIGS. Here, prior to the description of the flowchart of the column base design support program, the outline of the characteristic portion in the column base design support program of the present embodiment will be described. The details will be described later. The column pedestal design support program of the present embodiment is a diagram schematically showing an array of a plurality of column pedestals to be subjected to a strength test as shown in FIG. (Referred to as a key plan) on the display means 3 so that the column base mark indicating the column pedestal on the key plan can be identified from the respective test results of the bending moment M and the shear force Q applied to the column pedestal. In addition, it is characterized in that it is visually distinguished and displayed with a mark, color tone, etc. according to the level of the test value, and this key plan makes it possible to determine whether the balance between stress and proof stress is appropriate. This makes it possible for a designer to easily and visually comprehend, and to reduce the time and efficiency of the design work.

In the key plan, the positions of the column bases on the design drawing are replaced with the positions of the key plan coordinate system, and the column base marks are displayed at the replaced positions. For this reason, for example, the pillar arrangement on the actual design drawing is the same as that shown in FIG.
9B, the key plan is arranged and expressed in the coordinate system of the key plan as shown in FIG. 9B. Here, the case where the coordinate system of the key plan is an XY orthogonal coordinate system is illustrated.

Now that the features of the present embodiment have been clarified, the operation of the pedestal design support program will be described with reference to FIGS. When recognizing that the column pedestal design support program has been started by a click operation of the mouse 5 by the designer, the CPU 19 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, the designer instructs to display a proof strength window showing the proof strength results, and the CP
When U19 recognizes this instruction, it displays a tolerance test window on the display means 3.

FIG. 10 is a view showing an example of the proof stress test window. This proof stress window is a window configured based on the proof stress test table group 18 and has almost the same configuration as the conventional proof stress test window shown in FIG. 20, but a column base position definition field 21 is newly added. It differs in that it is provided. The other parts except for the column base position definition field 21 are the same, and the description thereof will be omitted because they are duplicated. Column base position definition field 2
1 will be described in detail below. CPU19
Recognizes that the list button 23 of the proof stress window has been clicked, displays the column / street symbol definition window superimposed on the proof stress window (S2).

FIG. 11 is a diagram showing an example of a pillar / street symbol definition window. Usually, on the design drawing, a street symbol for specifying a pillar position is attached to each pillar row. For example, in the example of FIG. 9A, R1 to R3, X1 to X3, S1 to S
4 corresponds to the street symbol. In the pillar / street symbol definition window, an input for defining such a street symbol by a number of each coordinate axis of the key plan coordinate system (hereinafter referred to as a coordinate axis street number) is performed (S3). By defining the street symbol by the coordinate axis street number in this manner, FIG.
As a result, a highly versatile design support system applicable to the strength test of a complicated column arrangement as shown in FIG. Then, as defined here, the symbol is displayed on each coordinate axis displayed on the key plan.

That is, FIG. 11 shows a symbol input field 31 for each of the numbers 1 to 10 as the X-axis coordinate axes.
Symbols X1 to X10 are input to the Y-axis coordinate axis numbers 1 to 10, respectively.
12 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.

The street symbol input fields 31, 32
May be directly input using the keyboard 7, or the numbering setting support fields 33 to
35 may be used. Specifically, for example, FIG.
In the case where X1 to X10 are to be input as shown in FIG. 1, first, the X-axis radio button is selected in the axis selection field 36, and X is serially entered in the initial character input field 33a of the numbering setting support field 33. 1 in the number input field 33b
By inputting 1 and 10 into the serial number start value setting field 33c and the serial number start value setting field 34d, respectively, and pressing the numbering button 33e, X1 to X10 are automatically entered in the street symbol input field 31. Can be entered.

When it is desired to input the same number as the coordinate axis, the number can be easily input by using the numbering setting support field 34. That is,
By inputting the number of the last cell having the same value in the end cell input field 34a and pressing the numbering button 34b, the current cell where the cursor is located in the input field 31 is input to the end cell input field 34a. The same value as the number according to the coordinate axis is automatically input up to the cell that has been set. Also, clear field 35
Is to clear all the contents input from the current cell where the cursor is located to the cell input to the cell specification field 35a by pressing the clear button 35b. It should be noted that these numbering setting support functions are naturally provided by a column base design support program.

As described above, 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 stores the definition information input here to the hard disk 15. While writing, the symbol definition window is closed and the control is returned to the proof stress window.

The proof stress window (see FIG. 10) is obtained by adding a column base position definition field 21 to the conventional proof stress test window shown in FIG. 20 as described above. The position of each pedestal is defined using this.

More specifically, X on the design drawing
When the column pedestal specified by 1, 1 is defined on the proof stress test window, as shown in FIG. 10, the column pedestal is defined in the X input field 21a and the Y input field 21b of the column pedestal position definition field, respectively. A coordinate axis number 1 corresponding to the symbols X1 and Y1 is input to specify the position. Note that the horizontal fields 22a, 22a, 2b, and 2c of the X input field 21a and the Y input field 21b respectively.
2b, a symbol is automatically displayed as corresponding to each. The column base position is defined with reference to the design drawings. The contents defined as described above are stored in the pillar / street symbol definition table 20 in the hard disk 15. FIG. 8 is a diagram showing a pillar / street symbol definition table. As shown in FIG.
It is managed separately.

This column base position definition input is performed for all column bases to be subjected to the proof stress test (S5). Thereafter, when a key plan creation instruction operation is performed by operating the mouse 5 or the like by the designer (S6), The CPU 19 generates a key plan based on the proof test table group 18 and the column / street symbol definition table 20, and displays the key plan on the display unit 3 (S7).

FIGS. 12 to 16 show an example of the key plan. FIG. 12 shows the entire key plan.
FIG. 16 shows the key plan actually displayed on the display means 3. The key plan has been briefly described above, but will be described in detail here. In the key plan (see FIG. 12), coordinate axes in the two-dimensional coordinate system (here, the X axis and the Y axis in the rectangular coordinate system) are displayed at predetermined intervals, and each axis has a column / street symbol definition window ( Symbols as defined in FIG. 11 are sequentially displayed in the X-axis direction (right direction in the figure) and the Y-axis direction (upward direction in the figure). Then, for all of the column bases defined using the strength test window (see FIG. 10), a column base mark □ is displayed at each column base position, that is, at the intersection of the coordinates specified by the street symbol, and further, the column base is displayed. At the upper right of the mark □, stress information on the column base is displayed in a table format.

Pillar mark □ displayed on the key plan
Is visually distinguished and displayed by the display color according to the stage of the test result of the pedestal corresponding to the display position. The processing performed by the CPU 19 for this display is as follows. The CPU 19 performs a proof test table group 1 for each column base.
From the column base test table of FIG. 8 (see FIG. 7), for each column base,
The maximum value of a plurality of test values for each stress of the bending moment M and the shear force Q is searched, and the display color of the stage to which each maximum value belongs is determined based on the color definition table shown in FIG. The pedestal mark □ is displayed in the display color, and each maximum value is displayed in a corresponding portion of the table on the upper right of the pedestal mark (in the upper and lower cells on the lower left side of the table). This table will be described later in detail.

Here, the column pedestal mark □ indicates that the bending moment M is within □ and the shearing force Q is within the □ frame, and the column pedestal mark □ is filled with the display color of the maximum verification value of the bending moment M. Column base mark The color of the frame is displayed in the display color of the maximum test value of the shear force Q. Explaining in a specific example, in FIG. 13, the maximum value of the test values of the bending moment M of the column base 41 at the coordinates X1 and Y1 is 0.56.
Since the maximum value of the test values of the shearing force Q is 0.97 when the value exceeds 0.75 and 0.75 or less, and is 0.75 or more and 1.0 or less, the color definition in the reference numeral 51 in FIG. As a result, the inside of the pedestal mark □ is painted in light blue, and the pedestal mark □ frame is displayed as a yellow bold line. Note that the reference values (0.5, 0.75) for classifying the test values in FIG. 17 can be arbitrarily changed.

The CPU 19 determines the bending moment M for each of the same column type from among a plurality of test values managed in the column base test table (see FIG. 7) of the proof stress test table group 18. And the maximum value of the shearing force Q, respectively.
The color definition of reference numeral 52 of 7 is applied with priority. That is,
The column base 42 in FIG. 14 has a maximum test value of the bending moment M of 1.28, and therefore, according to the color definition of the reference numeral 51 in FIG.
Of those whose model number is "□ -500-8M-42",
Since the test value of the bending moment M corresponds to the column base having the maximum value, the inside of the column base mark □ frame is displayed in dark pink. The column base 43 in FIG. 15 has a model number of “□ -500-8M-
48 ", both the bending moment M and the shear force Q have the maximum test values, so the color definition of reference numeral 52 is applied to both the column base mark □ frame and the column base mark □ frame. Displayed in dark pink and bold red lines.

Next, the output contents of the table displayed in the upper right corner of the column base mark □ will be described. FIG. 18 is an explanatory diagram of output contents. The display processing performed by the CPU 19 when displaying this table is as follows. The CPU 19 extracts, for each column base, the column code, the column base model, and the determination result from the strength test information table, and the respective maximum test values of the bending moment M and the shear force Q retrieved earlier, Extract the load case that resulted in the maximum test value and the judgment result,
It is displayed in a table format at the upper right of the corresponding column base mark. In addition,
If the test value exceeds 1, a design change is required, so that identifiable information is displayed. Specifically, the column base 44 in FIG. 16 has the maximum value of the bending moment M exceeding 1, and its contents (* 3) are displayed in the table. Note that this 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 the table.

From the key plan thus configured, the designer can visually grasp the stress-proof strength balance of the entire column base to be subjected to the strength test. Then, in order to check whether there is a column base that requires a design change, 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 by searching for a column base mark that has been changed, a column base mark whose design is to be changed is changed in order to change the column base model. Click the strength test sheet for the column base (proof test window)
Is displayed on the display means 3. Then, referring to the judgment result of the output content table, an appropriate column base model is selected from the data at hand based on the current stress-proof strength balance, and is input to the column base model input field 24 on the strength test window. The calculation ON button 25 is pressed.

When the calculation ON button 25 is pressed, the CP
U19 recalculates test values for all column bases on the key plan based on the changed column type, and updates the strength test table of the hard disk. Then, the designer gives an instruction to display the key plan again to confirm the determination result after the change of the column base type.
The key plan is displayed based on the strength information table updated with the recalculated data. The designer confirms the displayed key plan, and if further changes are necessary, the same processing as above is repeated.

In the column base 45 of FIG. 14, the inside of the column base mark □ is white, and the column base mark □ frame is indicated by a thin black line. This implies that in this column base model (□ -500-8S-42), the respective strengths of the bending moment and the shear with respect to the stress are larger than necessary and can be changed to a model with a smaller strength than now. I have. As described above, the degree of balance between stress and proof stress can be easily grasped visually by the column base mark, and thus a detailed economic design can be achieved.

As described above, key plan confirmation and column base type change are repeated, and when a good balance between stress and proof stress is obtained, the column base design is completed (S8).

FIGS. 10 to 13 show the case where the omnidirectional display tab 61 is selected and the key plan based on the test results for both X and Y in the column axis direction is displayed. It is also possible to select the X direction display tab 62 or the Y direction display tab 63 to switch to key plan display when the column axis direction is limited to one direction. At this time, the CPU 19 receives an input from the designer, recognizes which tab has been selected, obtains a strength test result for the recognized tab direction from the strength test table, generates a key plan, and displays the key plan. Perform the process shown above.

Further, the key plan shown in FIGS. 12 to 16 is a key plan based on the test results in both the X and Y directions of the column axis as described above, and has both the bending moment and the shear force. Are displayed simultaneously, but the long-term load, short-term load, and ultimately, the combination of column axis direction, stress type (bending moment, shear force), vertical load and horizontal load based on horizontal force direction (right, left) It is also possible to limit and display the combination of loads.

When the column pedestal design is completed as described above, a print window is displayed by operating the mouse 5 by the designer, and when a print instruction is input on the print window (S9), the CP
U19 prints and outputs the key plan displayed on the key plan window by the printer (S10). The printed key plan corresponds to the key plan shown in FIG.

When recognizing that the display instruction of the column / column base list window has been made by clicking the mouse 5 on the main window, the CPU 19 displays the column / column base list window (not shown). I do. This pillar
The 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 column bases to be subjected to the strength test.

As described above, according to the present embodiment, the key plan which schematically shows the arrangement of the column pedestals to be subjected to the strength test is displayed on the display unit 3, and each column on the display unit 3 is displayed. Leg marks are visually distinguished and displayed according to the stage of each test result of bending moment and shear force,
Since the test result can be visually identified from each column base mark, the designer can easily grasp the balance between stress and proof stress of each column base. Therefore, the time required for the design work can be reduced, and the design work can be made more efficient.

Further, since the margin of the proof stress can be easily confirmed from the display colors of the pillar pedestal marks, detailed economical design can be easily performed.
