Behavior of Regular Steel Moment Resisting Concentrically Braced Frames (MRCBFs) in Seismic Zones
Abstract eng: An equation is proposed to improve the design of medium-rise ductile steel moment-resisting concentrically braced frames. The equation was derived by defining the minimum strength ratio for the resisting columns of the moment frames and the bracing system to have consistent strong column – weak beam – weaker brace collapse mechanisms assumed in the design premises of international building codes. The expression is supported with the pushover analysis of 26 ductile steel MRCBFs, with different heights and two different bracing configurations. From the analysis of the research results a strong relationship is found between the collapse mechanism and the building height, beams stiffness and the conceptual design for the bracing system.
