Recent earthquakes in which many concrete structures have been severely damaged or collapsed. About 60% of the land area of our country is susceptible to damaging levels of seismic hazard. We can’t avoid future earthquakes The research concentrates on a computer based push-over analysis technique for performance-based design of reinforced concrete building and steel building works subjected to earthquake loading. In the investigation, nonlinear static analysis of analytical model of four story Reinforced concrete building and steel building is conducted for local seismic conditions. Pushover analysis is an advanced tool to carry out static nonlinear analysis of framed structures. It is used to evaluate non linear behavior and gives the sequence…show more content…
Dinesh2 In the scenario, Steel framed structures plays an important role in construction industry because they are cost efficient, sustainable, durable, ductile and safe. To analyze the structure under seismic loads, the deformed geometry and the non-linear behavior of the structure is to be considered. Hence to determine the performance of the structure, non-linear or pushover analysis is performed. The pushover testing has been carried out on two frames namely bare frame and Steel braced frame. The research concentrates on a computer based push-over analysis technique In this present study, nonlinear analysis of Steel frame using ANSYS 14.5 under the horizontal loading has been carried out.

• M.K Rahman, M. Ajmal & M.H Baluch (2012) This paper presents a nonlinear static analysis for seismic performance evaluation of an existing eight-story reinforced concrete frame-shear wall building in Madinah. The building has a dome, reinforced concrete frame systems at different floor levels. The seismic displacement response of the RC frame-shear wall building is obtained using the 3D pushover analysis.

• S.P. Akshara (2015) The scope of the present study aims at evaluation of RC buildings designed according to IS 456:2000. The non-linear static pushover analysis procedure has been used in this regard The non-linear methods can give an Idea regarding the pattern of the plastic hinge formations and thus aid in the performance based seismic
