Abstract

Objectives: To discuss the effect of shear wall and its location on the linear and nonlinear behavior of irregular buildings with different eccentricities. Analysis: The behavior of eccentrically loaded buildings with and without shear wall is compared using linear static, linear dynamic and nonlinear static analysis with the help of a finite element based software. The parameters considered are Base shear, Storey drift, Torsion and Reinforcement in columns and hinge formation in the structure. Findings: The study concludes that provision of a box type shear wall at the core gives the best behavior but it is not desired from architectural point of view. Hence shear wall on the outer edges is more advisable to improve the behavior of asymmetric buildings. The location of shear wall do not have significant effect on the nonlinear behavior except that the position of hinges vary. Novelty: The study of effect of shear wall location in eccentrically loaded structures, especially its nonlinear behaviour gives a more precise idea on provision of shear wall.

Abstract

This paper discusses the complex behaviour of asymmetric structures; a study on the influence of variation in eccentricity due to mass asymmetry (using different magnitudes of asymmetry and different magnitudes of mass) on the linear and nonlinear behaviour of structure using response spectrum and static pushover analysis. The study is done using ETABS 9.7.4 software. The study concludes that increase in eccentricity, mainly increases the torsion due to seismic forces and does not have significant effect on the lateral displacement of the structure. This increase depends on both the magnitude of mass and the magnitude of asymmetry.
