Abstract

One of the most useful way to resist against earthquake is using coupling beam of steel shear walls. The steel shear wall’s behavior depends on several factors such as stiffness, ductility, strength and so on. But, it has the shear cracks in coupling beam. In this paper, the effect of Carbon Reinforced Fiber Polymer (CFRP) on coupling beams has been evaluated to find out the improvement in ductility, stiffness and its strength. In order to do this research, the commercial edition of ABAQUS software is used. The results show that, using CFRP sheets can improve the load capacity of coupling beams.
