侧向荷载下木框架剪力墙受力性能的有限元分析

Finite Element Analysis of the Mechanical Properties of the Wood Frame Shear Wall Under Lateral Load

随着现代木结构建筑在国内的推广应用,木结构的试验与理论研究工作在我国也逐步展开,其中对木框架剪力墙(简称木剪力墙)的研究也取得了较多成果。笔者基于木剪力墙结构在侧向水平荷载作用下的试验研究,利用有限元分析软件ABAQUS建立分析模型,主要研究无洞墙体、开门洞墙体在单向与反复荷载作用下的荷载-变形关系以及受力特点。将有限元模拟结果与试验结果对比分析表明,所建模型能够很好地模拟木剪力墙抗侧性能以及墙体应力状态和变形特点,模型能为木剪力墙抗侧性能的理论分析提供较好的借鉴。

With the application of modern wood structure building in China,the experiment and theoretical research of wood structure has been gradually developed in China,and the research of wood frame shear wall has made some achievements.Based on the experimental study of wood frame shear wall structure under lateral load,the model of the wall was established to study the mechanical properties of the wall without opening and wall with door opening under one-way as well as cycling lateral load through using the finite element analysis software ABAQUS.After comparing the finite element simulation results with experimental results,the model can be a good simulation of the stress and lateral deformation characteristics of wooden shear walls,and provide a good reference for the theoretical analysis of lateral load resistance of wood frame shear walls.
