PLAN IRREGULAR RC FRAMES: COMPARISON OF PUSHOVER WITH NONLINEAR DYNAMIC ANALYSIS

T. Mahdi, V Soltan Gharaie

Open publisher page 22 citations

Abstract

In this paper, the seismic behavior of three intermediate moment-resisting concrete space frames with unsymmetrical plan in five, seven and ten stories are evaluated by using pushover analysis. In each of these frames, both projections of the structure beyond a reentrant corner are greater than 33 percent of the plan dimension of the structure in the given direction. The performance of these buildings has been investigated using the pushover analysis. Results have been compared with those obtained from non-linear dynamic analysis.
