COMPARATIVE STUDY ON SEISMIC PERFORMANCE OF HIGH-RISE BUILDING WITH ENERGY DISSIPATION AND OUTRIGGER BELT TRUSS SYSTEM

This research paper is about the investigation on the seismic performance of a high-rise building with outrigger belt truss system and damper as energy dissipation system. Control of the lateral deflection and inter storey drifts is the major challenge to overcome in the execution of high-rise buildings while subjected to lateral loads. Utilization of outrigger and belt truss framework is a possible method to improve the structural behavior of the high rise building under lateral loads. The performances of a 40 storey RC building with different numbers and locations of outrigger belt truss systems and dampers are compared with that of the conventional building. Non-linear time-history analysis was employed using the program SAP2000 to study the behavior of the building sunder three different seismic waves
