摘要
利用结构弹塑性地震反应理论,采用理想弹塑性模型,通过结构非线性分析程序,对双层柱面网壳进行了地震作用下的弹塑性分析.对杆件进入塑性后网壳的地震响应和抗震性能进行了较详细的研究,同时给出了对网壳工程设计有指导意义的结论.
A theoretical study is presented on elastic-plastic seismic performance of lattice shells.Using a nonlinear computer program, the seismic response analysis of a double-layer cylindrical lattice shell is carried cut A detailed analysis is performed to investigate the elastic-plastic performance of the shell under strong ground motions. The elastic-plastic behaviors for displacements of nodes and stresses of members of the structure are discussed. Some suggestions are given for guiding the design of lattice shell in seismic regions.
