模擬地震動作成方法
Document Type and Number:
Japanese Patent JP7438005
Kind Code:
B2
Abstract:
To obtain a simulated earthquake motion appropriately representing the time-course characteristics of an actual earthquake motion, while conforming to a target acceleration response spectrum.SOLUTION: A simulated earthquake motion creation device 100 calculates an acceleration response spectrum vector {Sa} of a simulated earthquake motion corresponding to a candidate acceleration time history vector {ai}. The simulated earthquake motion creation device 100 calculates a time-course characteristic vector {En} representing the time-course characteristics of a simulated earthquake motion corresponding to the candidate acceleration time history vector {ai}. The simulated earthquake motion creation device 100 sets a candidate output vector {o} including the acceleration response spectrum vector {Sa} and the time-course characteristic vector {En}. The simulated earthquake motion creation device 100 calculates an error vector {r} between a target vector {otar} and the candidate output vector {o}. The simulated earthquake motion creation device 100 calculates a new candidate acceleration time history vector {ai} to reduce the size of the error vector {r}, and when a predetermined condition is satisfied, acquires the new candidate acceleration time history vector {ai} as the acceleration time history vector of the simulated earthquake motion.SELECTED DRAWING: Figure 1
