Abstract

In the final stage of a structural design, the response of a structure as designed under a given set of loads and forces must be compared with the performance objectives. In this paper, a simple static analysis procedure is proposed to estimate maximum structural and member response in the seismic design of reinforced concrete (R/C) frame structures. The distribution of story drifts and member ductility demands along the structural height was studied by comparing the results of nonlinear earthquake response analyses and static push-over analyses. The results of two push-over analyses could reasonably estimate the distribution of ductility demands during an earthquake if the story shear distribution in the push-over analyses were taken to be the sum and the difference of the first two modes.
