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...

The slotted-hidden-gap (SHG) connection eliminates the need to reinforce slot region of hollow structural sections (HSS) braces concentrically braced frames (CBFs). However, existing design approach for SHG connections is rather empirical and limited by range geometries materials that had previously been tested. A general based on findings a large-scale parametric study presented in this paper,...

yielding elements (ye) are among those devices that not only help control structural damages, but make better seismic behavior by concentrating the frames in some removable part of the structures. ye are located at the intersection of concentric braced frame (cbf) in a rectangular shape. in this paper, seismic behavior of the frames with ye will be investigated. for this reason, 5 braced steel ...

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...

Superelastic Shape Memory Alloy (SMA) is accepted when it used as connection in steel structures. The seismic behaviour of steel frames with SMA is being assessed in this study. Three eightstorey steel frames with different SMA systems are suggested, the first one of which is braced with diagonal bracing system, the second one is braced with nee bracing system while the last one is which the SM...
