摘要
采用正交展开方法模拟的地震动随机过程作为动力激励,基于极值概率密度演化方法,对一种新型复杂建筑结构——巨子型有控结构体系,进行了基于随机地震过程作用下的动力可靠性分析,求得MSCSS在单一失效准则及复杂失效准则下的可靠度。结果表明非平稳地震作用下巨子型有控结构体系可靠度高于巨型框架的动力可靠度,在多遇地震情况下比传统的巨型框架结构更为安全。
We conduct the orthogonal expansion of the mega-sub controlled structural system( MSCSS) subjected to nonstationary random earthquake excitation,which is a new complex architectural structure. Then we use the probability density evolution method( PDEM) and the equivalent extreme value event to do the dynamic reliability analysis of the MSCSS and the mega frame structure( MFS) respectively,thus obtaining the reliability of the MSCSS under the simple failure criteria and complex failure criteria. The analysis results,given in Tables 1 and 2,and their comparison show preliminarily that the earthquake resistance reliability of the MSCSS subjected to nonstationary random earthquake excitation is higher than that of the MFS subjected to the same and the MSCSS is safer than the MFS.
