Concentrically braced frames (CBFs), designed using the conventional linear elastic method without seismic proportioning and detailing requirements, are referred to as Conventional CBFs (CCBFs) in this study. They widely used moderate low areas North America due ease of design economy. Without a code specified dedicated fuse member dissipate earthquake induced energy, or prescribed yield/failur...

Design and detailing requirements of seismic provisions for concentrically braced frames ~CBF! were specified based on the premise that bracing members with low KL /r and b / t will have superior seismic performance. However, relatively few tests investigate the cyclic behavior of CBF. It is legitimate to question whether the compression member of CBF plays as significant a role as what has bee...

This paper experimentally investigates the cyclic inelastic performance of concentrically braced frames with and without cold formed steel stud ~CFSS! infills designed to laterally restrain braces and delay their buckling. Specimens have either diagonal tube or solid bar braces with and without CFSS and U brackets providing out-of-plane and in-plane buckling restraint. Behavioral characteristic...

In the recent past, several research studies have highlighted that prescriptions reported in codes for design of structures with concentric braces chevron configuration are often not effective preventing yielding or buckling non-dissipative members and ensuring collapse mechanisms characterised by uniform damage braces. To investigate reasons these deficiencies, this paper seismic response conc...
