Seismic analyses of reinforced concrete frame structures are performed using the finite element method to identify and propose efficient modeling strategies for the development of fragility information for frame structures. For efficient analysis, an approach of concentrating nonlinearity into possible failure sections while other portions of the simulation model remain elastic is suggested. The method is applied to a frame structure by inserting cohesive interface elements at failure sections and calibrating the constitutive model for the interface elements. Two shake table tests of a lightly reinforced concrete 3-story frame building are simu- lated to investigate the accuracy and efficiency of the suggested modeling strategy for the reinforced concrete frame buildings.
