Abstract :

               During last few years, we have faced terrifying earthquakes, Killari (September 29, 1993) and recently Bhuj earthquake (January 26, 2001). Where most human injuries and economic losses are caused by the failure of engineered structures, particularly buildings. Recent earthquakes, in which large economic losses have been suffered, confirm this noticeably. Experience gain from the recent earthquake of Bhuj, 2001 demonstrates that the most of buildings collapsed were found deficient to meet out the requirements of the present day codes. Under such circumstances, seismic qualification of existing buildings has become extremely important. Seismic qualification eventually leads to retrofitting of the deficient structures. In this paper a seismic retrofit using shear wall and different bracing system based on the pushover analysis will be proposed for the life-safety target performance of the existing building. A nonlinear static pushover analysis using the displacement coefficient method, as described in FEMA 356, is used to evaluate the seismic performance of the existing building. The traditional methods of seismic retrofitting are reviewed and their weak points are identified. Repairs can lead to increased stiffness, strength, and failure-deformation.
