摘要：Outrigger systems have been efficient in stiffening the structure against lateral loads like wind orearthquakes. So, in order to know more about their effects on the structure and their behaviour under earthquake loads,an overall seismic evaluation and comparison of 30 storey building located in zone 2 with conventional slab systemhaving a central shear wall core and 1 outrigger level and flat slab system having central shear wall core and 1 outriggerlevel is demonstrated in this paper. Pushover analysis was performed using ETABS 9.7.4 on the models and using theperformance parameters like Base force, Displacement, Storey drift, Spectral acceleration and Spectral displacement,relevant conclusions were drawn. The outrigger struts for both conventional and flat slab case was placed at 0.5h whichis the most beneficial location for an outrigger level in a structure according to the literatures. Also, the status andlocation of plastic hinges at the performance point obtained from static pushover results showed that performancelevels for almost all the models were found to lie in between Life safety to Collapse prevention range.
