STATIC ANALYSIS OF MULTISTORIED RC FRAMED BUILDING USING ETABS

Abstract

In the present study modeling and analysis of G+3 storeys (4 storeys excluding headroom) RC building is done in ETABS Software. Totally thirteen 3D RC framed building models are considered for the seismic analysis having plan dimensions of 10.5m x13m with a storey height of 3.2m each and the depth of foundation is taken as 1.5 m (Total height of building including depth of foundation and headroom is 17.5 m). As per IS-1893: 2016, Part-1, the equivalent static lateral force method is considered for all thirteen buildings for all Zones (II, III, IV & V) and Soil conditions (Hard, Medium & Soft Soil) respectively. The response quantities are mode period, storey displacement, and base shear obtained from those models, and the results are tabulated. Further work has been carried out for the cost analysis of with and without earthquake building models. The concrete quantity and steel quantity has been estimated separately and tabulated for different zones and soil conditions. The estimated costs are compared for all building models (with and without earthquakes) and the results are tabulated. The displacement and base shear values are maximum in zoneV, and soil-3 when compared with all zones and soil conditions. The estimation cost is maximum in zone-V compared with all other models
