摘要

The multi-ribbed composite wall structure is a new, light and energy-saving residential building structure with good earthquake-resistant performance, it is very important to study the structure system for improving the wall innovation and building saving energy in our country. In the paper, a structure model is presented for the modelling of shear sliding in masonry and crack and crush in member basing on a three-parameter hyperbolic yield criterion proposed by Shing. Non-linear finite element method adopting a backward-Euler return mapping algorithm have been conducted to analyze the composite wall. Experiments of composite wall specimen have been carried out to evaluate the structure model. It shows that the structure model proposed by this paper can capture the failure mechanisms of the composite wall comparing with the experimental and numerical result. Consequently, the non-linear finite element models provide a unique capability for the analysis and evaluation of the composite wall structure.
