Seismic & Wind Analysis of Multistory Building: A Review

A. A. Kale, S. A. Rasal

Abstract: Now a day the tall structures like skyscrapers are widely adopted in major cities in India. Many major cities are very closer to the coastal area & almost all of them comes under the live seismic zone which is big problem for high rise multistorey buildings. The manual analysis of such a complex structure are too hectic & time consuming. It is very necessary to find the solution on this issue instantly. So the wind & seismic analysis of the structures done by the advance software CSI ETABS. In this proposed study four different shapes of same area multistorey model is generated & tested by the ETABS under the guideline of IS-875-Part3 & IS1893-2002-Part1. The behavior of 15, 30 & 45 storey building has been studied. The Dynamic effects also find by Response spectrum method. All the parameters like Story displacement, Story drift, Base shear, Overturning moments, Acceleration & Time period are calculated. After comparing the all building shape results we can conclude that which section is convenient & either seismic or wind effect is critical.
