| 摘 要： | 基于动力弹塑性分析,介绍了三个大跨度场馆的大震下安全度评价和优化设计,通过对核心筒和钢构件截面的优化,形成合理的结构破坏模式,达到节省钢材并减少剪力墙和主要受力构件在大震下塑性屈服的目的。大震下动力弹塑性分析不仅为第二阶段设计提供了验算手段,同时也为第一阶段结构设计优化提供了依据。

| Abstract: | Based on the elastic-plastic dynamic analysis,the evaluation of the safty degree under strong earthquake and the optimization of the structural scheme of three large-span gymnasiums are introduced.The optimization of core tube and the cross-section of steel members is advantaged to form the rational failure mode,save steel and reduce the shear wall and the main component plastic yield under strong earthquake.The elastic-plastic dynamic analysis under strong earthquake not only provides a means of checking f... |
