Abstract

This paper presents the effect of response spectrum analysis and construction sequence analysis on the setback steel structure. In this study, the proposed building is eleven storey setback steel structure. The length of the proposed building is 78ft and width is 66ft. The effective height of proposed building is 142ft. This building is located in Mandalay. So it is situated not only destructive zone but also basic wind speed, 80mph. The structure is composed of special moment resisting frame SMRF . Structural elements are designed according to AISC 360 10 2 . Load consideration and stability checking for proposed building are based on ASCE 7 10 3 . The analysis and design of the proposed structure model is done with the help of ETABS 2016 version 16.2.1 software 6 . The present study involves response spectrum analysis RSA and construction sequence analysis CSA , which are done on a setback steel structure and the structural analysis results such as storey displacement, maximum axial force, maximum shear force and maximum bending moment of the structural frame elements are compared. The maximum storey displacement with CSA is increased by 56 than the displacement with RSA. The maximum axial force on columns with CSA is increased by 48 than axial force with RSA. The maximum shear forces and bending moments with CSA are more than shear forces and bending moments with RSA.
