Stability of X-Bracing Systems with Traditional Bolted Connections
This paper deals with the design for stability of steel concentrically X-bracing frames built with HSS bracing members. Traditional slotted-tube connections with bolted shear splices are used for the bracing members. Both single- and double-shear splices are investigated. Full-scale quasi-static cyclic test program showed that instability of the discontinuous braces initiated through bending deformations of the connection plates, prior to overall buckling of the bracing members. Elastic stability analysis is performed to assess the effective buckling length and compressive resistances of the bracing members with double shear connections. Brace resistances are also obtained from an analytical model that accounts for inelasticity effects and geometrical imperfections of the brace connections. Numerical predictions are compared to test results and a numerical example is included to illustrate the method.
