Embodiment

[0032] This embodiment provides a full-stage high-efficiency energy-consuming replaceable coupling beam combined with viscoelasticity and eddy current. The functional device includes a mild steel assembly (metal damper) and a damper. The mild steel assembly includes a first mild steel part 2 and a second mild steel part 9. One end of the first mild steel part 2 is connected to an end plate 1, and the second soft steel part 2 is connected to an end plate 1. One end of the steel piece 9 is connected to the other end plate 1, and a damper is connected between the first soft steel piece 2 and the second soft steel piece 9, and the damper is a composite body composed of an eddy current damper and a viscoelastic damper. Combining the shear energy dissipation advantages of the three dampers, a replaceable connecting beam with high shear energy dissipation strength is formed comprehensively; the eddy current damper and the viscoelastic damper form a complex in a cross-fitting manner, w...

Abstract

The invention relates to an energy dissipation type connecting beam. The connecting beam comprises two end plates which are detachably connected with a non-energy-consumption section, and an energy consumption device which is connected with the end plates. The energy consumption device comprises a soft steel assembly and a damper. The soft steel assembly comprises a first soft steel part and a second soft steel part, wherein one end of the first soft steel part is connected with one end plate, one end of the second soft steel part is connected with the other end plate, the damper is connectedbetween the first soft steel part and the second soft steel part, and the damper is a composite body composed of an eddy current damper and a viscoelastic damper. Compared with the prior art, the connecting beam improves the structural comfort, and achieves the full-stage energy consumption.

Description

technical field [0001] The invention relates to the field of anti-seismic and disaster prevention and mitigation of civil engineering structures, in particular to an energy-consuming coupling beam. Background technique [0002] With the rapid development of my country's social economy, high-rise buildings are more and more common. As the main lateral force structure of high-rise buildings, shear wall structures are prone to stress condensation in earthquakes, and brittle failure of wall limbs yields, which will cause huge disasters and loss. For this reason, the ductility design of the shear wall structure is proposed in the code, and the coupling beam is required to be the first line of defense of the aseismic system of the combined shear wall. The main structure of the force wall is safe. However, if the accumulated plastic damage of the coupling beam is not reinforced or repaired in time, it will inevitably lead to damage to the coupling beam, and the shear wall will be ...
