DYNAMIC ANALYSIS OF SYMMETRICAL & UNSYMMETRICAL HIGH RISE STRUCTURE WITH CURTAILED SHEAR WALL

Abstract

The purpose of this research is to investigate   the   performance and behavior of the symmetrical and un-symmetrical high rise structures with shear wall curtailment subjected to seismic forces and result concluded in terms of base shear, axial forces, max. node displacement, storey drift, maximum shear forces and bending moment. Analysis showing that high rise symmetrical and un-symmetrical type of structures without shear wall have un-acceptable   performances for stability and serviceability of high rise structures due to seismic forces but both type of structure with full height shear wall have excellent performances. Similarly shear wall curtailment as in symmetrical high rise structure from 70% height of the structure and shear wall curtailment in un-symmetrical high rise structure from 80% height of the structure as compared to full height shear wall structures having variation in results only of 40% in symmetrical structure and 50% in un-symmetrical structures and all results also within required limits. Hence in this investigation we have defined the height of shear wall curtailment for symmetrical and un-symmetrical type of high rise structures reduces the cost, weight and enhances aesthetic view of the high rise structures.
