Abstract:
case studies of the design of an building employing three dimensional eccentrically braced frames as lateral force resisting system are discussed. The floor framing system consists of composite beamssupported by long span trusses, which are then supported by exposed composite columns. The lateral system is a dual system. The primary lateral system is made of four EBFs supported by the eight composite columns and folded around the four corners of the main building. The secondary lateral systemis a moment resistant space frame consisting of the floor trspace and the composite columnspushover and earthquake response history analyses indicate that the dual structural system possesses substantial reserve strength over the code prescribed minimum lateral Nonlinear sequence and the distribution, as well as the extent of the plastic hinge rotations observed from the analyses illustrate that the building is likely perform satisfactorily under severe seismic events
