A quasi-static cyclic test program was conducted on full scale X-bracing systems of the conventional construction and moderately ductile seismic categories. The study focused on the influence of typical bolted connections at the brace intersection point on the brace stability. HSS bracing members with single and double shear lap splice connections were examined. Braces built with back-to-back double angle sections were also investigated. The test specimens were designed and detailed in accordance with the CSA Si 6-09 standard. The test program showed that common mid-connections may trigger premature instability of X-braced frame assemblies. In most cases, inelastic response concentrated in the connections, which then became the energy dissipating elements of the system rather than the bracing members. This behaviour generally resulted in limited ductility. Locally increasing the flexural stiffness and strength of the connections could improve the stability response of the system.
