组合墙结构非线性分析模型

NONLINEAR ANALYSIS FOR COMPOSITE MASONRY WALLS

本文提出一种框墙模型，用以对开洞组合墙进行非线性分析。使用已有试验结果和非线性有限元分析对其进行了验证。将这种单元装入结构静力分析程序，对本文作者所完成的大开间灵活分隔住宅结构模型进行了非线性分析，与试验吻合较好，证明这一模型是可行的。该项研究为组合墙的设计与分析提供了可供使用的力学模型。

Composite masonry walls, which consist of masonry walls, tie columns and tie beams, possess many advantages and are widely used in China. However, it is difficult to have the structure analyzed, because of its complex working mechanics. In this paper, a new nonlinear analytical model called frame wall model is put forward. It was verified by nonlinear finite element analytical results and test results of two tested composite masonry walls. This model was also used to analyze a tested six story residential structure model and fine result was obtained. Conclusion is that the new model is feasible and effective.
