摘要
本文把具有解析递推格式的地震反应谱数值计算方法归结为单步法和两步法,并且给出了说明这两种方法传递算子具有不变特性的两个定理。利用这两个定理,本文较为简便和完善地推导了新的地震反应谱数值计算递推公式。文末通过计算对比研究,给出了同时计算绝对加速度、相对速度和相对位移反应谱的快速方法及相应的计算程序。
The numerical algorithm for computing earthquake response spectra which have the analytical recursion scheme is divided into the single and two step method in this paper. And two theorems are proposed to describe the unchanging characteristics of transmiting operator in the scheme for these two methods respectively. The new algorithms for computing response spectra are more conveniently and completely derived from the theorems. The fast algorithm for computing absolute acceleration, relative velocity and relative displacement response spectra at same time is suggested by comparing the algorithms, and the corresponding computer program is listed in the end of this paper.
