DESIGN AND SEISMIC RESPONCE OF HIGH RAISE RCC BUILDING WITH DIFFERENT ZONES WITH SHEAR WALLS

Abstract

Shear wall systems are one of the most commonly used lateral load resisting systems in high-rise buildings. Shear walls have very high in plane stiffness and strength, which can be used to simultaneously resist large horizontal loads and support gravity loads, making them quite advantageous in many structural engineering applications. There are lots of literatures available to design and analyze the shear wall. However, the decision about the location of shear wall in multi-storey building is not much discussed in any literatures. In this paper, therefore, main focus is to determine the solution for shear wall location in multi-storey building. In this study, a G+ 10 storeyed reinforced concrete (RC) building with varying ground slope as 0º, 5º, 10º, 15º and 20º without shear walls and incorporating shear walls symmetrically in plan and at peripheral corners have been considered for the analysis. Buildings are designed as per IS 456:2000 and later subjected to earthquake loads. The modelling and analysis of the building has been carried by Liner Static, Linear Dynamic analysis (Response Spectrum and Linear Time History analysis) using structure analysis tool SAP 2000. The main objective is to understand the behaviour of the building on sloping ground for the effect of varying height of the column in bottom storey and various positions of shear walls and to study the effectiveness of shear wall on sloping ground.
