Abstract
This paper investigates the earthquake-induced failure of high-rise steel moment-resistant frame buildings subjected to sequential long-duration ground motions. A fiber-element model was developed with considering the strength and stiffness deterioration caused by local buckling and low-cycle fatigue fracture. The modeling method taking account of strength and stiffness deterioration was validated by component test results of both column bases and beam-column joints. At the structural level, simulation results including both global and local behavior were compared with the shaking table test results of a high-rise steel building in Japan, which showed a reasonable prediction of its seismic failure up to collapse.
