Wind Analysis of Tall Building with Vertical Setback for Different Height & Area Ratio

Abstract

The Tall building is being used as much as possible, to live, to commercial and to make statue. It will be of all the building different shapes, design and Structure. From this point of view any building having different discontinuity in mass, geometry of Structure and stiffness. This discontinuity impart the irregularities in the structure. The collapse of high rise building due to irregularities like in symmetries of mass, stiffness, height ratio and geometry of structure. To keep this needs for a long time, we must find out the permissible irregularities to get the maximum building strength/ building life. For design of tall building we need to consider wind load. So, the effect of vertically irregularities in the wind analysis performance of structure becomes really important. Now we will study about behavior of high rise building with different vertical setback and Area ratio on different models of moment resisting rigid frame structure with optimum location of shear wall. In this scrutinize, G+30 story rigid frame structure is taken with two different aspect ratio 1:4:9 and 1:1.56:2.25 for different set-back position in the structure. The set-back provided in the structure are Setback at 15&25 story, Setback at 15&20 Story, Setback at 10&25 Story, Setback at 10&15 Story, Setback at 5&20 Story and Setback at 5&15 Story. Story drift, Story Displacement, Base shear Result are revaluated. On the basis of this result best structure to be discover.
