Comparison of Influence of Wind and Earthquake Forces on Low-Rise and High-Rise Multi Story Structures
This paper presents a comparative study of the severity effect of earthquake and wind forces on a multistory building. It is very essential to consider the effects of lateral loads in the design of reinforced concrete structures. It determines the critical design loading for a multistory buildings subjected to different basic wind speeds (39, 44, 47, 50, 55 m/s ) and earthquake zones(II,III,IV,V). In the present study the response of low-rise and high-rise multistory buildings are analyzed with earthquake loads based on IS 1893:2002 and for wind loads IS 875:1987 code. When a building is situated in a particular wind and earthquake zone, the major designing loads for the particular building can be decided using these results. After a detailed study the low-rise buildings are more affected when subjected to earthquake forces and high-rise structures are equally effected by wind forces when compared to earthquake forces.
