The nonlinear static analytical procedure (Pushover) as introduced by ATC-40 was applied for the evaluation of existing design of a reinforced concrete frame, in order to examine the applicability of the pushover for evaluating design of new buildings. Potential structural deficiencies in the frame were assessed by the code seismic-resistant design and pushover approaches, for the sake of comparison. In the first approach, the potential deficiencies were determined by redesigning under one selected seismic combination in order to show which members would require additional reinforcement. In the second approach, a pushover analysis was conducted to assess the seismic performance of the frame and detect the locations of the plastic hinges. The paper shows that vulnerability locations revealed from the two procedures are significantly different, where the latter procedure tends to overestimate column strength, consequently, concealing earlier detection of column weaknesses. The paper provides rational explanations for the apparent discrepancy that can be taken into consideration in order to make pushover methodology applicable when designing or evaluating existing design of new buildings.
