Abstract: In this study considered, Performance of 20 storey building under lateral load with different structural systems, such as Rigid frame, Core and Outrigger structural systems under seismic loading with seismic zone ? at soil type III (soft soil) and reduction factor 5 for special RC moment-resisting frame. It is evaluated by Response Spectrum analysis for different load combinations as per IS: 1893:2002. Analysis of above mentioned structural systems are carried-out using E-TABS 2015 software. To check the performance of the building by considering following parameters such as, roof displacement, base bending moment of inner and edge columns and base core moment for core structural system and outrigger structural systems. The object of the study is to determine the degree of effectiveness of different locations of outrigger structural system to increase the performance and sustainability of the building.
