Comparative Study of Wind And Earthquake Analysis On Multi-Storeyed Rc Framed Building By Etabs

Abstract

Analysis on building for seismic and wind forces is very important because earthquake and wind have damaged many structures from decades. It is very important to analyze any structure because it will be subjected to many forces during its life span which may affect the building. The affect on the performance of the building when subjected to seismic and wind forces hugely depend on the zone, where structure is actually located. In India we have four zones, zone Ⅱ, zone Ⅲ, zone Ⅳ and zone Ⅴ. Out of these four zones zone Ⅴ is very much prone to earthquake. This study reports the comparative study of wind and earthquake analysis on multi-storeyed RC Framed building using ETABS. This study explores the potential of G+11 RC Framed building against seismic and wind forces. This analysis reveals that the base shear due to earthquake is same in both X and Y direction as 2366.1757 KN and study also displayed same base shear due to wind in both X and Y direction as 2026.9818 KN. Present analysis also explored the same mode periods for three different mode shapes due to earthquake and wind as 2.004s, 2.044s, 1.773s and respectively. This study also revealed the higher storey displacement for G+11 in both seismic and wind analysis as 75.738mm and 43.787mm respectively. It also concluded the higher storey shear of G+11 in both seismic and wind analysis as 501.0178KN and 97.5433KN respectively. This analysis displayed earthquake forces are more dominant than wind forces as the height of building increases.
