Abstract:Due to the complexity plan and strict seismic requirement, the buckling restrained braces (BRB) are used in the Expo Center. Section parameters determination, connection design and product acceptance specifications of BRB are the main issues to be performed to design BRBs. Combined with the application of BRB in the EXPO Center, the design procedures of BRB are proposed, including the material behavior of steel core, the calculation and requirement of stiffness, capacity and deformation of BRB. In addition, the desirable detail and capacity calculation method in connection design are advised. Based on the code for acceptance of steel structures, the product acceptance specifications are provided for BRB in the EXPO Center.
Keywords:buckling restrained brace; seismic performance; section parameter; connection design; acceptable specifications
