Behaviour and design of a (G + 5) multi storey framed structure under different loading condition

A multi storey building is a building that has multiple floors above ground in the building. Multi-storey buildings aim to increase the floor area of the building without increasing the area of the land and saving money. Analysis of such type of structures involves lot of complications and edacious calculations by conventional methods. This research examines the design and analysis of a multi-storey building (G + 5) under various forces, including dead load (DL), Live load (LL), wind load (WL), and seismic load. It highlights the importance of adequate strength in preventing collapse, as manual load calculation is cumbersome for structural engineers. In order to identify the most vulnerable building among the models considered, the various analytical approaches are performed to identify the seismic demands in both linear and nonlinear way. It emphasizes the need for seismic research and planning to protect buildings from earthquakes. The study examines the seismic response of a residential G + 5 reinforced cement concrete (RCC) frame structure using STAAD Pro software and a static approach, following IS 1893(Part1):2016. Results of the numerical analysis indicate that any storey, especially the first storey, should not be softer than the storeys above or below. Non-uniform mass distribution also contributes to the increased response of the buildings. The irregularities, if required to be provided, need to be catered to by appropriate and extensive analysis and design processes. Based on these findings, some guidelines are proposed to make buildings safer to seismic excitations.
