Evaluation Of Idealized Capacity Curve Generation For Reinforced Concrete Framed-Structures Subjected To Seismic Loading

The designing of R/C framed structures subjected to seismic excitation generally is performed by linear elastic method, while current trend of the codes of practice is moving toward increasing emphasis on evaluating the structures using nonlinear static pushover (NSP) approaches. Recently, several N...
