Abstract: The design philosophy of strong-column-weak-beam (SCWB) in which plastic deformation is predominantly allowed to occur in beams while columns remain essentially elastic is commonly adopted in seismic design codes for ...

Abstract: A buckling restrained knee braced truss moment frame (BRKBTMF) is a novel steel structural system that combines steel trusses with buckling-restrained braces (BRBs) to form an alternative seismic force–resisting system. ...

Abstract: The use of energy as means to derive seismic design forces is discussed in this paper. The energy balance concept used in deriving seismic design forces for single-degree-of-freedom systems is extended and used to derive ...

Abstract: The objective of this paper is to present a seismic evaluation procedure based on an energy balance concept. The method is based on a framework that utilizes energy demand and capacity diagrams. The skeleton force–displacement ...

Abstract: The design and behavior of a ductile structural system called a knee-braced moment frame (KBMF) are presented in this paper. The design of this structural system is based on a capacity-design concept that results in ductile ...
