Abstract

Provided is a mountable and replaceable type low yield point compound energy dissipation multiple-seam type coupling beam system. According to the multiple-seam type coupling beam system, open seam can be conducted on an ordinary coupling beam, a compound energy dissipation device which is constituted by low yield point steel, energy dissipation lead and the like can be assembled to the open seam of the coupling beam, thus sufficient energy dissipation and seismic mitigation can be conducted through the compound energy dissipation device in an earthquake, the situation that severe destroying occurs on a shear wall body is avoided, the situation that brittle failure of the coupling beam is prevented, and thus the overall safety of the structure is guaranteed. The mountable and replaceable type low yield point compound energy dissipation multiple-seam type coupling beam system mainly comprises the reinforced concrete multiple-layer coupling beam in the shear wall structure, upper and lower part covering plates of the compound energy dissipation device, the low yield point steel, the energy dissipation lead, environmentally friendly coating, a bolt and a bolt hole. According to the mountable and replaceable type low yield point compound energy dissipation device, mountable construction can be achieved, the device is time saving, and it is convenient to replace the device after the earthquake. According to the coupling beam system, obvious adjusting does not need to be conducted on a design scheme, the cost is low, and the system is safe and environmentally friendly, convenient in construction, easy in maintenance after the earthquake, and high in reliability.
