摘要

为了解决密肋复合墙板中填充砌体在受到循环荷载作用时的平面数值分析问题，该文基于等效单轴应变原理，建立了一个宏观砌体平面材料模型，并将该材料模型与平面应力单元相结合，开发了相应程序。最后，将平面模型与纤维模型相结合对密肋复合墙板进行了模拟分析。结果表明：该模型在模拟处于平面应力状态下的密肋复合墙板时具有较为理想的效果，在满足计算精度的同时，又能充分体现砌体构件的宏观现象，可较为直观地获得砌体结构的应力分布云图，验证了该模型的正确性和适用性。

Abstract

A simple constitutive model was developed to calculate the in-plane stresses of multi-ribbed composite walls subject to cyclic loadings. The equivalent strain concept was used to develop the macro in-plane model for masonry walls with the in-plane model then implemented in plane-stress finite elements. The in-plane model and a fiber model were then combined to simulate the stresses in multi-ribbed composite walls. The results show that the model accurately simulates the stresses in a multi-ribbed composite wall under plane stresses. The accurate results fully reflect the macroscopic phenomena in the masonry components and the stress distribution cloud diagram in the masonry structure is more intuitive. These results verify the accuracy and applicability of the model.
