Abstract: As per the previous records of earthquakes, there is an increase in the demand of use of earthquake resisting structures. So it is necessary and prime concern of designer to design and analyses the structures by considering seismic effect to provide adequate safety to structure against lateral loads. Many existing RC frame buildings located in seismic zones are deficient to withstand earthquakes. Insufficient lateral resistances, improper shape and poor detailing of reinforcement are the main reasons for inadequate seismic performance of multi-storey building. Shear wall system is one of the most commonly used lateral-load resisting technique for high-rise buildings. Shear walls have very high in-plane strength and stiffness, which can be used simultaneously for resisting large horizontal and gravity loads. In tall buildings, it is very important to ensure adequate lateral stiffness to resist lateral load. The aim of this work is to determine the most effective shape of building with their optimum location of shear wall in multi-storey buildings. For this purpose five different shaped (i.e. square shape, rectangular shape, T-shape, U-shape and H-shape) fifteen storeyed building models each has been with their optimum location of shear wall. Building plan area and shear wall area are same for all different shaped fifteen storeyed building models. Models are analyzed in earthquake zone IV for comparing storey displacement, storey drift, storey shear and time period of buildings. Earthquake load is calculated as per IS: 1893-2016 (Part-1), the various parameters like response reduction factor, importance factor, zone factor are taken from IS: 1893-2016 (Part-1) and are applied to the buildings located in Zone IV. The buildings are modeled and analyzed using software ETAB 2017 and finally concluded that the square shaped building with their optimum location of shear wall is more effective other than different shaped buildings to control the lateral displacement in up to 15 stories buildings.
