地震作用下砌体结构倒塌过程仿真分析
SIMULATION ANALYSIS FOR THE COLLAPSE RESPONSE OF
本文利用动力有限元程序LS—DYNA，分别对一、二、三层砌体结构在地震作用下的倒塌，进行了力学分析和仿真，并根据计算结果进行了参数讨论。仿真计算的结果与真实倒塌过程非常接近，说明通过适当的选取计算参数和计算模型，可以对这种特殊的复杂破坏过程进行模拟分析和仿真。通过预演或再现倒塌过程，发现结构在地震作用下的薄弱环节，为抗震设防提供依据。
In this paper,make use of software LS-DYNA to simulate and analyse one-floor masonry ,double-floor masonry,three-ply masonry under the earthquake.Discuss parameters in accord of the result.If the computer simulation is similar to the truth,that means we have chosen correct parameters and module.I can recur it on computer .It not only help us to recur the collapse on the computer and found the weakness in the structure under the earthquake but also provide the basis in design.
