Abstract - The majority of the time when using FEM software to examine a multistorey building frame, a complete model is created, then the model is applied with loads at once. However, in real structures, the actual load is applied to the structure in phases as the building is constructed. Construction sequence analysis, a non-linear static analyzing technique that analyses the structure step by step by establishing an automatic construction load case in FEM software, was therefore developed to address the existing problem. The current investigation, which is being done on a G+25 residential structure, uses the CSI ETABS 2016 programme to do standard Equivalent static analysis and construction sequence analysis for the dead load situation. According to Indian Standard Code IS:1893-2002, the structure is of the RC and steel frame type and has a floating column, with two sets of models RC and steel having the same position as the outer column and the other two sets of models RC and steel having the same position as the inner column. It is located in zone 2. Results from the analysis that are generated using the CSA and ESA are abstracted, including bending moment, shear force, and column axial force.
