Performance-based earthquake engineering (PBEE) requires accurate estimation of the seismic demand and capacity of structures.

Abstract
Performance-based earthquake engineering (PBEE) requires accurate estimation of the seismic demand and capacity of structures. To tackle this task, incremental dynamic anal-ysis (IDA) is employed herein to investigate the performance of moderately ductile moment resisting frame (MD-MRF) office buildings designed according to the current building code of Canada and steel design standard. For simulating the nonlinear response from yielding to failure, the MD-MRF beams were modelled in the OpenSees software as beam with finite length hinge elements. The plastic hinge segment was made of fiber cross-sections. In addi-Tion, a proposed low-cycle fatigue model capturing the MD-MRF beams failure is presented.
