摘要
详细推导了Bouc-Wen模型的全量和增量形式的数学表达式,并将其应用于地震作用下结构的弹塑性时程分析,降低了恢复力特性曲线中拐点处理的难度,减小了计算量。实例计算结果表明,Bouc-Wen模型的计算结果和双线性模型的计算结果非常接近。
The whole deal and increment deal mathematical expression ot Boue-wen moael is deduced in details and also applied in the elastoplastic time-history analysis of structures under the seismic action, whereby the difficulties to deal with the inflection points in the restoring force behavior curve are lowered in such a way as to reduce calculation quantities. The results from the practical example calculation indicated that the calculated results by Boue-Wen model are found to be very similar to those by the bilinear model.
