The analysis and design of structures are influenced by earthquakes. A structure’s behaviour under particular load combinations is determined through an analysis process. The process of determining suitable requirements for the construction is called design. Manually, the design of the structure and the analysis would take a long time. Any structure’s study and design can be completed quickly using the software. The main goal of this study is to analyse and construct a commercial building using various slab configurations, including flat slabs, grid slabs with drop panels, and conventional slabs. A structure is considered commercial if at least half of its floor area is devoted to business purposes. Buildings with various slab layouts and the impact of seismic and wind forces has been analysed by utilising SAP2000 software. The engineering software programme SAP2000 is used for structural analysis and design. The IS 456-2000 code book is used for analysis and design, and M30 grade concrete and Fe500 steel are used. According to Design Code IS-875, dead load is taken (Part 1). Live loads are calculated in accordance with Design Code IS- 875 (Parts 2) and (Parts 3), while earthquake zones 3 and 4 are used for analysis. Both 1.2 (DL + LL + EQ) and 1.5 (DL + LL + WL) combination are taken into consideration. A number of issues have an impact on how well building’s function, including story drift, base shear, and story displacement are key factors in determining how well structures respond to wind and seismic loads. The results are presented using tables and bar charts. Story displacement increased along with story height. In comparison to all other slab arrangements used in the wind and seismic load analyses, the results demonstrate that buildings with grid slabs are more stable.
