Minimum cost performance‐based seismic design of reinforced concrete frames with pushover and nonlinear response‐history analysis
Previous studies compare results of pushover and nonlinear response‐history analysis of predesigned reinforced concrete frames. The present study employs nonlinear response‐history analysis and pushover analysis with the N2 method in a computational framework for the minimum cost performance‐based seismic design of reinforced concrete frames according to the fib Model Code 2010 methodology and compares their obtained design solutions in terms of cost and structural performance. It is found that the minimum costs of pushover‐based designs are similar to the costs from response‐history analysis for regular frames but the pushover‐based designs can be more expensive for irregular frames. Furthermore, the pushover‐based designs are not guaranteed to satisfy performance objectives when subjected to response‐history analysis even when more than one lateral load distributions are applied.
