Abstracts: Traditional reinforcement methods in concrete have been accepted for many years as common practice. Recently confinement has become important for improving ductility & strength and for preventing shear failure. Now-a-days internal confinement & external confinement has been very popular for seismic up gradation of existing concrete specimens. The focus of this project is to compare the behavior of unconfined, confined and retrofitted concrete specimens using innovative materials. With the evolution of technology, construction industry has witnessed enormous advancement in the production of concrete and construction materials. Such materials have helped the community to produce structures that consume less energy, environmental friendly, have less carbon foot print and are more durable with longer life expectancy. However, old buildings that didn’t follow the latest technology are no longer considered to have the previous qualities. In addition, they are no longer considered safe due to the deterioration of the concrete, steel or both. As a result, researchers continued to investigate different types of materials that can best strengthen and rehabilitate aging concrete structures and render them safe. The main focus of our study is to enhance the load carrying capacity and ductility of the concrete specimens by means of providing confinement and applying the various retrofitting techniques.
