Abstract

The aim of this study was assessing the seismic performance of three types of mid-span connections in the cross bracing systems including: the mid-span connection with cover plates, the flanged connections and the braced ductile shear panel (BDSP). For this purpose, the linear buckling and post-buckling behavior of the cross braces with the aforementioned connections having nonlinear geometries and materials were numerically analyzed. The results were compared to the results of the common connection. According to the results, use of the cross braces with mid-span connection together with cover plates and flanged connections due to creating continuity in the mid-span connection, cause coordinated buckling of the discontinuous diagonal members (or so-called second mode buckling) and thereby improved compression performance of the cross braces. In addition, use of the ductile shear panel in the mid-span connection led to more energy dissipation by cross braces and prevented buckling of the diagonal bracing members.
