NON-LINEAR FINITE ELEMENT MODELING OF A MULTI-RIBBED COMPOSITE WALL STRUCTURE
A new energy-saving composite wall structure is a new residential building structure characterized by low weight, saving energy and good aseismic performance, which is mainly constructed with multi-ribbed composite slabs, concealed frame and floor by means of assembling and casting. In the paper, a Non-linear finite element 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. 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 show 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.
