Abstract

Multi-ribbed frame grid (hereinafter referred to as MRFG) is an important part of Multi-ribbed composite wall and consisted of outer frame and ribbed grid. The reinforcement of outer frame is the main influence factor on the performance of MRFG. In this study, an MRFG specimen under laterally cyclic and axial loading in literature is numerically simulated with 5 kinds of different reinforcement ratio of outer frame, by a general finite element software and user-defined material model. The influence of different reinforcement ratio of outer frame on the mechanical behavior of MRFG has been discussed.

Keywords: Multi-ribbed frame grid (MRFG), multi-ribbed composite wall, mechanical behavior, numerical simulation.
