In high rise building or multi storey building, soft storey construction is a typical feature because of urbanization and the space occupancy considerations. Reinforced concrete framed buildings with in-fills are usually analyzed as bare frame, without considering the strength and stiffness contributions of the in-fills. However when subjected to a strong lateral loads, infill panels tends to interact with bonding frame and may induce a load resistance mechanism that is not accounted for the design. These provisions reduce the stiffness of the lateral load resisting system and a progressive collapse becomes unavoidable in a severe earthquake for such buildings due to soft storey. This storey level containing the concrete columns were unable to provide adequate shear resistance, hence damage and collapse are most often observed in soft storey buildings during the earthquake. Open first storey is a typical feature in the modern multi-storey constructions in urban India. Such features are highly undesirable in buildings built in seismically active areas; this has been verified in numerous experiences of strong shaking during the past earthquakes. Response spectrum analysis is chosen for the analysis of the model since it provides response to the applied loads and spectra conditions. In the current study the focus is on the performance and behavior of a structure with soft storey at different floors with the help of response spectrum method. For analysis purpose, six different cases of model are studied using ETABS V.16.03. A G+20 building with simple square plan is considered, as per IS 456:2000 and IS 1893:2002.

The performance-based modeling and analysis of a 10-story building with special moment resisting frame (SMRF) as seismic force-resisting system and SMRF with shear wall (Dual System), is presented here. In performance based seismic analysis, evaluates how building is likely to perform. It is an iterative process with selection of performance objective followed by development of preliminary design, an assessment whether or not the analysis meets the performance objective. For structural design and assessment of reinforced concrete members, the non-linear static analysis has become an important tool, method can be used to study the behaviour of reinforced concrete structures including force redistribution. The paper presents a simple computer-based pushover analysis technique for performance-based design of building using non-linear static analysis to developed the capacity and demand curve, push over curve, rotation of hinge for CP (collapse prevention) performance point. The seismic response of RC building frame and dual system in terms of performance point and the effect of earthquake forces on multi storey building frame with the help of pushover analysis is carried out in this paper. In the present study the building frame is analyzed using ETAB'S V.16.03, as per IS 456:2000 and IS 1893:2002 and for non-linear parameter ASCE-41-13 and EC8-2004 is used.
