Use of Shear Wall Belt at Optimum Height to Increase Lateral Load Handling Capacity in Multistory Building: A Review

Abstract

The improvement of the tall building has been quickly expanding around the world because now a days, people try to live in multistory structures. As per design criteria, the main focus is to resist the structures from lateral loads mainly from severe earthquake. The shear wall came into practice to resist lateral loads. But why complete shear wall is to be used from foundation to top. That's why shear wall belt criteria came into existence. The study is conducted on a 25-storied high-rise residential building. A standard floor plan with plinth area of 825 m 2 used in this work. Different cases are created with shear belt at different floors. Response spectrum method with SRSS combinations used to determine various parameters such as base shear, maximum nodal displacement in longitudinal and transverse direction, drift values and load cases that creates maximum drift. With this view, this paper presents the criteria of provision of shear belt at different heights with the use of Staad pro software. Recommendations made to choose optimum location of wall belt position in structure along with the best of all.
