Nonlinear static behaviour of rc frame buildings during construction stages

Abstract

Multi-storied reinforced concrete (RC) frame buildings nowadays constitute a large extent of the building stock in urban India. Usually, multi-storey buildings are analysed at the final stage but in reality loads are sequentially applied at every stage of construction. So in the present study, the influence of the story height on capacity has been attempted to be investigated through analysis of five RC frame buildings during their intermediate construction stages. Here earthquake force is considered to be applied in all the full buildings along with their intermediate stages and pushover analysis is carried out to determine possible damage of structural members with increase in height of the buildings. The present study gives an insight on the vulnerability of the structural members of building liable to seismic damage.
