Abstract

A number of experimental studies have been reported in recent literature about the beneficial effects of infill walls on the seismic response of RC frames. CFRP sheets are used as an external bracing system for retrofitting of infilled RC frames. The common mode of failure of such frames is debonding of the CFRP. In the current study, behavior of CFRP retrofitted infilled RC frame was investigated with 3D micro model using shell element in modeling concrete and infill panel, and two-noded truss element for the RFT bars using Abaqus\standard package. The adhesive layer was modeled using cohesive surface-to-surface interaction model. A great agreement was found between the FEM results and modes of failure using cohesive interaction and that presented in the experimental work in the literature.
