提出了两种可拆卸式消能减震钢桁架式连梁,连梁的上下弦杆与钢筋混凝土剪力墙内的钢结构预埋件铰接,而腹杆与弦杆采用螺栓连接,且腹杆由屈曲约束支撑或屈曲约束钢腹板等消能装置组成。通过2个1/2比例的钢桁架连梁试件的低周反复荷载试验研究了该可拆卸式钢桁架连梁的抗震性能。研究表明:设置屈曲约束支撑和设置屈曲约束钢腹板的钢桁架连梁具有较好的强度和位移延性,其破坏模式表现为消能减震装置的塑性破坏;连梁试件的滞回曲线饱满,耗能能力良好;建议的钢桁架连梁能够满足高烈度区连梁抗震性能的需求,能够应用于高烈度区的联肢剪力墙结构中。 Two kinds of detachable energy-dissipating steel truss-type beams are proposed. The upper and lower chords of the connecting beams are hinged with the prefabricated steel structures in the reinforced concrete shear wall, while the webs and the chords are bolted and the belly The rod is supported by buckling restraints or energy dissipation devices such as buckling restraining steel webs. The seismic performance of the detachable steel truss girder was studied by low-cycle cyclic loading test of two 1/2 ratio steel truss beams. The results show that the steel truss girder with buckling restraint brace and buckling restrained steel web has good strength and displacement ductility, and the failure mode shows the plastic failure of energy dissipating damper; the hysteretic curve Full and good energy dissipation capability. The proposed steel truss beam can meet the seismic performance requirements of even beams with high intensity, and can be applied to the joint-shear wall structure with high intensity.
