摘要:由于地震波得不确定性,现有针对地震对地表结构物得力学性质得理论计算存在着各种不足,为了给现有得理论计算和
经验分析做出一点帮助,应用钢筋混凝土弹塑性理论和钢筋混凝土非线性有限元分析方法,采用大型显示动力分析软件 LS-DYNA
对已有得地震作用下地表结构物的动力响应做出分析。模拟结果和已有实际情况基本相符。通过结构物的弹性时程分析曲线可以
得出结论,弹塑性动力时程分析在复杂高层结构中是十分必要的,它能在误差允许得情况下判明结构的屈服机制、薄弱环节及可
能的破坏类型,是判断结构抗震性能的最贴近实际的方法。

Abstract: Due to the indeterminacy of the seismic wave path, there are some deficiencies in calculation and
theory of dynamics which exist for the surface structures affected by earthquake. To help both the theoretical
arithmetic and the empirical analysis. with elastic-plastic analysis and non-linear finite element analysis of the
reinforced concrete, a response of dynamic analysis is made for the surface structure affected by earthquake by
LS-DYNA. Result of simulation basically accords with the state of the time-curve of flexible
analysis ,we can conclude that, it is very necessary to make a time-dynamic analysis of elastoplastic
