Abstract
Due to devastating effect of earthquake in the past decade, it is now important to consider the effect of earthquake while constructing medium to high rise buildings. Due to scarcity of space and shifting of people from rural to urban areas, it is now essential to construct high rise buildings. To counter the large size of beams and columns an alternative has been found for high rise buildings and is termed as shear wall. It has very high in plane stiffness and when situated in advantageous positions in a building, they can be very efficient in resisting lateral loads originating from earthquakes. However, we cannot provide shear walls at all the locations due to economic considerations. So it is very necessary to determine effective, efficient and ideal location of shear walls. Therefore, an attempt has been made to find the ideal location of shear walls in symmetrical structures. A 3-D analysis of G+14 storey shear wall structures has been carried out using the STAAD. Pro V8i software. Different models have been drawn by adopting different locations of shear walls. A comparative study has been done on six parameters, namely, storey displacement, storey drift, storey shear, base shear, bending moment, peak storey shear and time period of the structure between bare frame RC model and shear wall RC frame model. Linear dynamic method of analysis (response spectrum analysis) has been used following IS 1893 (Part l):2016. From the study, it has been observed that the lateral displacement, storey drift, bending moment and time period of the shear wall system decreases as compared to the bare frame. Base shear and storey shear value in the shear
wall structure increases as compared to bare frame structure. It is concluded that Boxshape shear wall system (located at the core of the building) significantly contribute to structure stiffness as compared to the other shear wall systems.
