Seismic performance of moment resisting steel frame subjected to earthquake excitations

Fadzli M. NAZRI, Pang Yew KEN

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 1,   Pages 19-25 doi: 10.1007/s11709-014-0240-3

Abstract: This study presents static and dynamic assessments on the steel structures.Pushover analysis (POA) and incremental dynamic analysis (IDA) were run on moment resisting steel framesSteel frames are subjected to nonlinear inelastic time history analysis for 14 different scaled groundThe IDA results show that the far field ground motions has caused all steel frame design within the researchto collapse while near field ground motion only caused some steel frames to collapse.
