摘要
西安东门城墙是我国的重点保护文物,对其研究意义重大.本文采用俞茂宏统一强度理论建立的弹塑性本构模型的动力有限元程序,输入El-Centro 波对其研究,得到了不同点的加速度响应曲线、位移响应曲线和最大加速度及最大位移,为古城墙研究提供了宝贵的资料.
The city wall of the East Gate in Xi′an has been named the historical relic by the State Council of China,so that it is the important significance for studying it.The dynamic analysis is investigated with input El centre wave by using the constitutive model of elasto plasticity that has been established by Yu Maohong′s unified strength theory.The response curves of acceleration and displacement at the different points,and the maximum acceleration and displacement have been obtained by the dynamic analysis of FEM.
