Recent earthquake surveys have highlighted significance of RC walls as an integral part of
structures. It was observed that RC wall structures sustained less damage in comparison to
structures that did not possessed RC wall. Researchers on the basis of their post earthquake
surveys concluded that RC wall buildings sustained damage because of flaws in design and
construction work. In this article experimental result of six RC shear walls is discussed. They
were designed under-reinforced to fail in flexure. Four out of these six specimens were
strengthened externally with CFRP strips bonded to wall panel and mesh anchors installed at
wall foundation joint. Two specimens, one RC and one CFRP retrofitted, were subjected to
static load test and four specimens, one RC and three CFRP retrofitted, were subjected to
cyclic load tests. The test result analysis discussion includes cracking pattern, stiffness,
ultimate load capacity, ductility, and energy dissipation.
