摘要
本文对大跨度结构抗震计算方法的近期发展作了简单的评述，在此基础上介绍了对平稳／非 平稳随机响应简便高效而且精确的虚拟激励算法。给出的三个例题表明用此方法已经可以在微机上 对较为复杂的工程结构进行计算。
Analysis methods of long span structures subjected to seismic actions are briefly reviewed. A highly efficienct and accurate approach-the pseudo excitation method is put forward for the stationary and nonstationary response analyses of such problems. Three examples are given which show that by use of the proposed approach, rather complicated engineering structures can be analyzed on microcomputers.
