Analysis of Tall Building by Various Types of Structural Forms under Earthquake Analysis

Abstract

Abstract: In the current world scenario, high-rise buildings are favoured due to the rapid rise in land values, land shortages, and to conserve land in rural areas for agricultural use. The construction of high-rise buildings primarily depends on wind and seismic loads. The performance of buildings depends on the structural configuration. The structural system of a high-rise building is designed to work with vertical gravity loads and mainly with lateral loads caused by wind and seismic activity. The structural system consists only of elements designed to transfer loads, all other elements that are not involved in the transfer of loads are called non-structural element. The research assist the analysis of G+16 Storey level with various mode of structural form used in tall building construction. The G+16 Tall building is modelled on CSI ETBAS for Zone 4 under seismic analysis by Response spectrum analysis. The various types of struural form used in the model 1 to model 6. The structural form consists of 1) Moment resisting frame 2) Building with Braced Frame Structure 3) Building with Hull-Core (Tube-in-Tube Structure) 4) Building with Shear Wall 5) Building with Composite 6) Building with Outrigger Structure. The research concluded that the model cases no 3 is optimised under the G+16 Storey building. Other than model 2, 4, 1 & 6 recommended for optimised case in descending order
