摘要
大跨度结构在受到演变随机地震激励且考虑行波效应时,其非平稳地震响应分析不但计及了振型间的耦合项及激励间的耦合项,而且有很高的效率.
By using the pseudo-excitation method,the non-stationary responses of structures subjected to multi-phase evolutionary random seismic excitations are analysed very efficiently,while the cross-correlation items either between the participant modes,or between the excitation points,are all included.
