Seismic Analysis of RC Building by Response Spectrum Method
Keywords:seismic zones, seismic analysis
Reinforced Concrete Frames are the most frequently adopted buildings construction practices in India. With budding economy, urbanisation and inaccessibility of horizontal space increasing cost of land and need for agricultural land, high-rise sprawling structures have become highly preferable in Indian buildings scenario, particularly in urban. With high-rise structures, not only the building has to take up gravity loads, but as well as lateral forces. Several important Indian cities fall under high risk seismic zones, hence strengthening of buildings for lateral forces is a prerequisite. In this study the aim is to analyze the response of a high-rise structure to pulverized motion using Response Spectrum Analysis. Dissimilar models, that is, bare frame, brace frame and shear wall frame are considered in Staad Pro. and change in the time period, stiffness, base shear, storey drifts and top-storey deflection of the building is experimental and associated.
