巨子型有控结构体系基于失效路径的结构抗震性态研究
|
摘要
过往对巨子型有控结构体系抗震性能的研究往往使用层间位移角作为性能指标,这对具有很多冗余构件的复杂结构体系来说是不够的。本文对此进行改进,将层间位移角与结构失效路径相结合,提出了结构抗震性态这一概念,用以描述结构在遭受地震破坏时的状态。最后建立了巨子有控结构体系三维有限元模型,利用本文提出的方法进行了抗震性态研究,从不同尺度分析了结构的破坏过程,其结果可为结构的抗震设计提供更加合理的建议。
In the past,the story drift was often used as a performance index for the study of the seismic performance of the mega-sub controlled structural system(MSCSS),which is not enough for a complex structural system with many redundant components.In this paper,the concept of the structure seismic behavior is proposed by combining story drift with structural failure path to describe the state of the structure in the case of earthquake damage.Finally,the three-dimensional finite element model of the MSCSS is set up,with the seismic behavior of the structure studied by the method proposed in this paper.The failure process of the structure is analyzed from different scales,which can provide more reasonable suggestions for the seismic design of the structure.
