Abstract
Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researches controlled use of this composite structural system in the United States for none and low-seismic hazard zones, this paper considers some of the latest provisions on RCS systems, which is to provide support in the development of performance based earthquake engineering. Also paper introduces a type of rigid steel beam to RC column connection and discusses its hysteresis curvature behavior and response modification coefficient of this hybrid system.
