Abstract :

     One kind of shear wall system is CSRCW which consists of two steel columns with stud and the column which is buried in reinforced concrete. This concrete cover can contribute to both load bearing and stiffness increasing. Studs are used to connect concrete to steel columns which have a very significant role in this regard. This research attempted to use the CFRP system in order to increase the load of the system. CFRP as a suitable method for increasing strength of structures has been the focus of research in recent decades. In 2012, D. Dan investigated the function of CFRP in reinforcing shear wall.  After verifying the Abaqus software, the outlet will also be examined to reinforce CFRP. As such, the base model without FRP reinforcement and strengthening model A are crossed X shape and model B are crossed K shape and model C just overlaps at the corners. The results showed an increase in the load of about 18% compared to the Model A which is the base model.
