四川汶川地震中砌体房屋大量破坏倒塌造成大量人民财产的损失,本文首先简要介绍ANSYS/LS-DYNA软件及材料模型的确定,砌体材料本构模型采用砖砌体和灰缝组成混合材料利用试验回归的参数确定,本文主要针对砌体结构构造措施进行分析,对比砌体结构无构造措施、设置传统构造柱砌体结构(无墙体拉筋)和设置传统构造柱墙体拉筋砌体结构三种。
The massive destruction of masonry houses in the Wenchuan earthquake in Sichuan caused a lot of loss of people’s property. This article first briefly introduced the determination of ANSYS/LS-DYNA software and material models. The masonry material constitutive model uses brick masonry and mortar joints to make up mixed materials. The parameters of the test regression are determined. This paper mainly analyzes the structural measures of the masonry structure, comparing the masonry structure without structural measures, setting the traditional structural column masonry structure (without wall reinforcement) and setting the traditional structural column wall lacing masonry Three kinds of structure.
