Comparative Study on Construction Sequence Analysis on Steel Structure without and with Floating Columns

This paper presents the 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 seismic destructive zone V, Mandalay. The basic wind speed is 80mph. The structure is composed of special moment resisting frame SMRF . Structural elements are designed according to AISC 360 10. Load consideration and stability checking for proposed building are based on ASCE 7 10. The proposed building is analysed and designed with the help of ETABS 2016 version 16.2.1 software. After response spectrum analysis RSA has done for the checking of the stability, then construction sequence analysis CSA is considered. And then the structural analysis results of the proposed building are studied such as axial force, shear force and bending moment of the structural frame elements. The effect of floating columns with CSA on axial force for the selected columns of proposed building is more influence from first to sixth floor level.The value of shear force with CSA is abruptly increased at the floated columns level and the other level are gradually decreased. The value of bending moment at the floated columns level is abruptly increased due to the effect of floating columns with CSA and the other level are gradually decreased.
