Analysis of High Rise Building for Lateral Loads and Its Comparison

In recent era India is fastest growing country across the globe and need of shelter with higher land cost in major cities like Mumbai, Delhi, Ahmadabad, Vadodara, Pune, etc. Where further horizontal expansion is not must possible due to land saturation. Recently there has been a considerable increase in the number of high rise building and the modern trend is towards more taller & more slender structures. It is very essential to consider the effects of lateral loads induced from wind and earthquakes in the design of reinforced concrete structures, especially for high-rise buildings. Thus the effect of lateral loads like Earthquake forces & Wind load are getting more importance and almost every designer is faced with the problem of providing adequate strength and stability against above lateral loads. Due to this in recent years wind & earthquake loads have become determining factor in high rise building design. Application example for buildings with different heights, floor weights and boundary conditions for both winds & Earthquakes such as intensity of wind pressure, gust factor (G), seismic zone coefficient (Z), the importance factor (I), Response reduction factor(R) and Average response acceleration coefficient (Sa/g) are analyzed and discussed for the purpose of comparison by using IS 456:2000, IS 1893:2002 & IS 875:1987 (part3).
