Rotary friction type replaceable energy dissipation connecting beam

Abstract

The invention provides a rotary friction type replaceable energy dissipation connecting beam which comprises a replaceable section positioned at a center of a connecting beam and non-energy dissipation sections which are distributed at two sides of the replaceable section and are arranged at positions of shear wall limbs, wherein two ends of the replaceable section are fixedly connected with the non-energy dissipation sections respectively, the replaceable section comprises two rotary friction energy dissipation damper monomers which are arranged back and forth and a profile steel plate whichis positioned at a middle space of the replaceable section, and the profile steel plate is integrally connected to the non-energy dissipation sections so as to enhance integrity and action consistencyof the replaceable section; a bottom plate of an outer sleeve of a rotary friction energy dissipation damper monomer is fixedly connected with a bottom plate bolt of an embedded cylinder and is respectively connected with a transmission rod bolt at the left side and the right side along different diagonal lines, and a high-damping rubber core is filled in a cylinder wall formed by the embedded cylinder and the outer sleeve. By the adoption of the rotary friction type replaceable energy dissipation connecting beam, the connecting beam can be properly adjusted according to requirements by meansof replacing the connecting beam, installation is convenient, and applicability is strong, so that the anti-seismic performance of a structure is improved, and the structure is used for restoring a functional shear wall structure system.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic and energy-dissipating vibration of civil engineering structures, and in particular relates to a rotary friction type replaceable energy-dissipating connecting beam. Background technique [0002] Combined shear wall structure is one of the lateral force-resisting systems widely used in high-rise buildings. In the design of combined shear walls, the coupling beams, as the first line of defense of the aseismic system, often suffer severe shear damage under the action of earthquakes exceeding the fortification intensity, which causes great difficulties for post-earthquake repairs. After an earthquake, buildings are often demolished and rebuilt due to excessive local damage that cannot be repaired, resulting in huge economic losses. Most of the replaceable energy-dissipating coupling beams that have been developed so far only start to consume energy under moderate and large earthquakes, and rema...
