  First, in step 100 in the figure, control is performed so that a prediction target information input screen having a predetermined format is displayed on the display 18, and input of predetermined information is waited in the next step 102.

  FIG. 11 shows a display state of the prediction target information input screen according to the present embodiment. As shown in the figure, on this screen, a message prompting the user to input information on the earthquake damage prediction target is displayed, and information on the building to be predicted for earthquake damage (hereinafter referred to as “prediction target building”). As the construction position of the building to be predicted (in this embodiment, an address), the type of building to be predicted (in this embodiment, any of wooden, S, RC, or SRC), and the evaluation target As the information on the number of floors and information on the earthquake to be predicted (hereinafter referred to as “predicted earthquake”), the earthquake occurrence frequency (in this embodiment, “rare” or “very rare”), and For inputting each type of earthquake information (in this embodiment, any earthquake type registered in the speed related information database DB2 such as “Tokyo metropolitan area earthquake”, “Tokyo northern earthquake”, etc.) A rectangular frame is displayed .

  When a prediction target information input screen as shown in the figure is displayed on the display 18, the user operates the keyboard 14 and the mouse 16 to construct the prediction target building, the type of the prediction target building, and the number of floors to be evaluated. Then, after inputting each information of the earthquake occurrence frequency of the prediction target earthquake and the type of the earthquake into the corresponding rectangular frame, pointing to the “end” button displayed at the bottom of the screen is designated with the mouse 16. Accordingly, step 102 is affirmative and the process proceeds to step 104.

In the next step 120, control is performed so that the generated earthquake damage prediction information is displayed on the display 18.

  FIG. 13 shows an example of the display state of the earthquake damage prediction information displayed on the display 18 by the processing of step 120 described above. As shown in the figure, the earthquake damage prediction information is a graph in which the adaptive response spectrum information calculated by the process of step 114 and the performance spectrum information derived by the process of step 116 are overlaid. Is displayed. In the figure, for example, “Koto-ku” is applied as the construction location of the building to be predicted, “RC construction” is applied as the type of building, and “5th floor” is applied as the number of floors to be evaluated. This is earthquake damage prediction information when “extremely rare” is applied as the earthquake occurrence frequency and “metropolitan area type earthquake” is applied as the earthquake to be predicted.

  In the example shown in the figure, six types of 1/150, 1/120, 1/100, 1/75, 1/50, and 1/30 are applied as interlayer deformation angles (maximum response deformation angles) R. The yield shear force coefficient Cy is changed from 0.2 to 0.8 in increments of 0.1.

  Therefore, in the next step 122, it is determined whether or not a curve indicating any performance spectrum information is designated within a predetermined period (1 minute in the present embodiment). If the determination is affirmative, step 124 is performed. And after deriving the interlayer deformation angle R corresponding to the intersection of the specified curve and the curve or straight line indicating the conformance response spectrum information, it corresponds to the derived interlayer deformation angle R and the type of building to be predicted The damaged image information to be read is read out from the damaged image information database DB4, and in the next step 126, control is performed to display the damaged image indicated by the read damaged image information on the display 18, and then the earthquake damage prediction program is terminated. To do. If a negative determination is made in step 122, the earthquake damage prediction program is terminated without executing the processing of steps 124 and 126.

  FIG. 14 shows an example of the display state of the damaged image information displayed on the display 18 by the processing of step 126 described above. Therefore, by referring to the damage image information shown in the figure, the user can visually and intuitively grasp the damage state corresponding to the designated yield shear force coefficient Cy.

The performance information (in this case, performance spectrum information) is acquired, and the reference seismic wave information indicating the reference seismic wave used as the basis of the seismic wave used for earthquake damage prediction is matched with the acceleration response spectrum indicated by the acquired response spectrum information (spectrum・ Fitting) generates compatible seismic wave information, and acquires the acquired performance information and When the present invention is not applied because the earthquake damage prediction information that can predict the damage status of the building due to the ground motion that is the target of earthquake damage is created based on the seismic wave information and the created earthquake damage prediction information is displayed Compared to the above, it is possible to easily predict the damage situation due to the earthquake of the building with high accuracy.

  Further, in the present embodiment, speed related information (here, maximum speed information) indicating the maximum speed of the ground surface at the construction position indicated by the inputted construction position information, which is the target of the earthquake damage, is further calculated. The acquired response spectrum information is calculated by multiplying the acquired response spectrum information by the magnification of the acquired velocity related information with the maximum velocity of the seismic wave indicated by the generated adaptive seismic wave information. Since the earthquake damage prediction information is created based on the acquired performance information, the earthquake damage can be predicted with higher accuracy.
