However very little work is found related to Analysis of irregular high rise building with shear walls at different locations. It is relevant that high rise building are increasing day by day hence its study is necessary for development point of view. So we thought to use Staad Pro V8i to analyze the certain irregular high rise building by changing the location of shear wall and see what the effects on structure are? The present work contains the experimental investigation on reducing the size of the member to make structure economical and efficient by locating shear wall at varying places in irregular shape building. The usefulness of shear walls in the structural planning of multistory buildings has long been recognized. When walls are situated in advantageous positions in a building, they can be very efficient in resisting lateral loads originating from wind or earthquakes. Reinforced concrete framed buildings are adequate for resisting both vertical and horizontal loads acting on them. Extensive research has been done in the design and analysis of shear wall high-rise buildings. However, significance of shear wall in high-rise irregular structures is not much discussed in literature. A study on an irregular high-rise building with shear wall and without shear wall was studied to understand the lateral loads, bending moment, shear effects. I. INTRODUCTION The tallness of a building is relative and cannot be defined in absolute terms either in relation to height or the number of stories. But, from a structural engineer's point of view the high rise building can be defined as one that, by virtue of its height, is affected by lateral forces due to wind or earthquake or both to an extent that they play an important role in the structural design. Shear walls are a sort of structural system that has lateral resistance to the building or structure. They are vertical components of the structure i.e. the horizontal force resisting system. They are made to counteract the result of lateral masses engaged on the structure. In residential construction, shear walls are straight external walls that usually provide all of the lateral support for the building. The design approach adopted in the Indian Code IS 1893(Part I): 2002 ‘Criteria for Earthquake Resistant Design Of Structures’ is to ensure that structures possess at least a minimum strength to withstand minor earthquake occurring frequently, without damage; resist moderate earthquakes without significant structural damage though some non-structural damage may occur; and aims that structures withstand major earthquake without collapse. Reinforced concrete (RC) buildings often have vertical plate-like RC walls called Shear Walls (Figure 1.1) in addition to slabs, beams and columns. These walls generally start at foundation level and are continuous throughout the building height. Their thickness can be as low as 150mm, or as high as 400mm in high rise buildings. Shear walls are usually provided along both length and width of buildings. Shear walls are like vertically-oriented wide beams that carry earthquake loads downwards to the foundation. Shear walls in high seismic regions require special detailing. Shear wall buildings are a popular choice in many earthquake prone countries, like Chile, New Zealand and USA. Shear walls are easy to construct, because reinforcement detailing of
