WIND LOAD ANALYSIS OF HIGH RISE BUILDING WITH AND WITHOUT SHEAR WALL AND ITS COMPARISONS

Abstract

Indian standard code IS 875(part-3)-1987 gives the specifications for wind load analysis on the different structures. The analysis is based on various steps provided for wind pressure intensity, wind load calculation by wind coefficients. Behavior of building by the wind pressure is dependent on the angle on which the wind is striking the structure. Wind load is dangerous for the high rise building ,hence various techniques are used to reduce its effects. Shear wall is a good option for this, which is effected up to approximate 70 stories. It is expected in this study that a shear walled structure will show the better result and stability against normal building without shear wall. This study compares the performance of buildings with and without shear wall in terms of deflection of at the different stories and various parameters. As a case study, a 40 storey building designed for Gravity loads(dead load +live load) as well as lateral load (wind load) as per IS:875(part-3)-1987 for wind zone IV is considered. This paper also provides other important conclusions on wind load design provisions and shear wall specifications.
