Tuned mass type yield energy-dissipation damping wall device

Abstract

The invention relates to a tuned mass type yield energy-dissipation damping wall device. An upper node plate and a lower node plate are connected with a main body structure in a diagonal way in the plane along the height direction of the main body structure; a steel core is connected with the upper node plate and the lower node plate, so as to form a single diagonal bracing system together with the main body structure; a bearing platform is arranged on the lower surface of the main body structure, a rail is paved on the bearing platform, and sliding limiting clamps are arranged on the two ends of the rail; a mass source front assembly, a mass source back assembly, an upper limiting plate and a lower limiting plate form a mass source of a TMD (tuned mass damper), pulleys are arranged on the lower surfaces of the mass source front assembly and the mass source back assembly, and are arranged on the rail, the middle part of the mass source is reserved with a certain gap, the steel core is clamped into the certain gap, and a rebound element and a damping element are arranged between the mass source end part and the main body structure, so as to form the damping wall device with double functions of tuned mass and metal yield energy dissipation.

Description

technical field [0001] The invention relates to a dual-function compound shock absorbing wall device, in particular to a tuned mass type yield energy dissipation shock wall device. It is a new technology invention in the field of energy dissipation and shock absorption of civil engineering structures. Background technique [0002] The tuned mass damper (TMD) is one of the technologies widely used in building vibration control at present. Partially offset the disturbing force input to the structure. Buckling-resistant bracing (BRB) is to arrange unbonded constrained units around the steel core to improve its stability, and then realize energy dissipation and shock absorption through the plastic deformation of the steel core during tension and compression. [0003] However, both traditional TMD and BRB have their own limitations: TMD takes up a lot of building space, is sensitive to changes in structural modal properties, takes a long time to start, and is slow to take eff...

Problems solved by technology

[0003] However, both traditional TMD and BRB have their own limitations: TMD takes up a lot of building space, is sensitive to changes in structural modal properties, takes a long time to start, and is slow to take effect. It has good wind-induced response and poor seismic response.

BRB has the problems of yield force limitation and material fatigue resistance. It has excellent seismic performance, but it has poor control of environmental vibration.
