Abstract:Shear walls as an integral part of structures have revealed to be of prime concern following earthquake surveys over the past few years. It was observed that shear wall structures sustained less damage in comparison to structures that did not possess shear wall. Researchers on the basis of their post earthquake surveys concluded that shear wall buildings sustained damage as a result of design and construction work flaws. In this article test data of CFRP strengthened short RC walls is analyzed. Three RC shear walls, designed to fail in shear, were subjected to static and cyclic load tests in which the loading amplitude was gradually increased till specimen failure occurred. Two out of three walls were strengthened externally with the help of CFRP material and mesh anchors at the wall foundation joint. The experimental results analysis consists in cracking pattern, stiffness, ultimate load capacity, ductility and energy dissipation.
