Pushover analysis of reinforcement concrete building
Abstract
In this study the seismic response of a six storied reinforced concrete building is analysed by displacement controlled pushover analysis. The building frame is simulated and analysed using the structural analysis and design software SAP2000. In nonlinear analysis, moment-curvature relationship is used to model plastic hinge behaviour. Thus it was developed for modelling the user defined hinges for beam and column sections. Moment (M) and interactive (P-M) hinges were assigned to the both ends of beam and column sections respectively. Top node displacement is incremented step by step up to the limiting displacement to obtain the pushover curve and the sequence of formation of plastic hinges and failure of beams and columns were recorded. The analysis results including the pushover curve and hinge formation are discussed. The maximum base shear capacity was found to be higher than the design base shear and hinges were formed in beams prior to columns
