Abstract

Abstract

As a new type of energy dissipation member， buckling-restrained braces （BRB） have been widely used in concrete structures. BRBs are connected with reinforced concrete members by embedded parts， which are the key force transmission components. In order to improve the bearing capacity of the embedded parts and facilitate construction， H-shaped steel embedded parts with web openings are proposed. The failure mode was explored through bending-shear tests and tensile tests. The test results showed that， due to the influence of bending moment， the failure mode of the bending-shear embedded parts involved the embedded part rotating as a whole around the loading end. This rotation caused the web strip far from the rotation point to fracture. Due to the insufficient shear capacity of the concrete beams， the failure mode of the tension embedded parts was shear failure of the concrete beams. Based on the test results， the finite element model was validated. The effects of loading point height， web depth， thickness， and anchor plate thickness on the mechanical properties of the embedded parts were analyzed using the finite element method. The results of the parametric analysis showed that an increase in bending moment reduced the bearing capacity of the embedded parts， while an increase in web height and thickness effectively improved the bearing capacity of the embedded parts； the anchor plate thickness， however， contributed little to the bearing capacity. Based on the test results and finite element analysis， combined with current specifications， a calculation method for the bearing capacity of H-shaped steel embedded parts with web openings was proposed.
