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.
Highlights
Steel shear wall is one of the most effective way to resist from earthquake
The shear wall behavior can be different in compressive area of the coupling beam
Barnes et al (2001) studied on the behavior of strengthening reinforced concrete shear wall with coupling beam using different plates and bolts which the results indicate improving in shear and flexural performance of coupling beam
Summary
Steel shear wall is one of the most effective way to resist from earthquake. The opening on the shear wall can be important in the architecture point of view, and it can improve ductility. The shear wall behavior can be different in compressive area of the coupling beam. There are two different ways to improve shear wall behavior with coupling beam.
