CQC-complete quaddratic combination,即完全二次项组合方法,其不光考虑到各个主振型的平方项,而且还考虑到耦合项,对于比较复杂的结构比如考虑平扭耦连的结构使用完全二次项组合的结果比较精确。 SRSS-Square root of sum square method,取各振型反应的平方和的方根作为总反应的振型组合方法。又称均方根法。©...
SRSS method is commonly used and known to give accurate estimates of responses for structures with widely spaced natural frequencies provided that the excitations are stationary random processes and each modal response is considered to be uncorrelated. However, seismic ground motions are not stationary ...
SRSS法和CQC法对于平面振动的多质点弹性体系,可以用SRSS法,它是基于假定输入地震为平稳随机过程,各振型反应之间相互独立而推导得到的;对于考虑平—扭耦连的多..
