PERFORMANCE BASED SEISMIC ANALYSIS OF RC BUILDING CONSIDERING THE EFFECT OF DUAL SYSTEMS

Abstract

Due to the present increase in world population, people in this world tend to occupy available locations present in any zone which also include zones falling in the high seismic zone categories. The buildings to be built in these seismic zones are more susceptible to earthquakes for obvious reasons, and the buildings constructed in such zones must be analysed and designed for the unpredictable earthquakes with unpredictable magnitudes by various lateral load resisting systems such as shear walls, bracings, tubular systems, coupled shear walls and even a combination of two load resisting systems called as dual systems. Present study includes linear-static and non-linear static analysis with different shear wall arrangements on dual systems such as flat slabs and shear walls & moment resisting frames and shear walls for different irregular plans using ETABS 9.7.4 software. Parameters such as point displacements, base shears, pushover curves are studied.
