Abstract
Generally the analysis of steel moment resisting frames has been performed without considering the accurate connection behaviors. However, a number of beam-column connections of the steel moment resisting systems raised sudden fracture resulted in enormous economical loss in recent earthquakes. In this study, the analytical modeling of Korean beam-column connections in steel moment resisting frames was proposed based on the experimental studies of other researchers. The adopted computer program for inelastic analysis was DRAIN-2DX, and the standard element type was set to the Element Type 10 in DRAIN-2DX for panel zones and beam-connections. The inelastic analysis results of the example structure with connection modeling were compared to those of the structures without connection modeling.
