Abstract

The invention relates to a composite self-resetting hydraulic damper, and belongs to the field of shock resistance and energy consumption. The composite self-resetting hydraulic damper comprises an upper friction plate, a lower friction plate, hydraulic buffers, a limiting plate, a CFRP plate, a friction material, SMA wires, upper connecting guide rods, lower connecting guide rods, outer frame plates, sliding limiting holes, connecting holes, an upper end plate and a lower end plate. The upper friction plate is in an N shape, and the lower friction is in a linear shape. The friction material is arranged between the upper friction plate and the lower friction plate. The upper end plate is arranged at the top of the upper friction plate. The upper friction plate is connected with a buildingby the upper end plate. The lower connecting guide rods are arranged on the lower portions of two ribs of the upper friction plate. The upper friction plate and an anchoring part are connected by theouter frame plates and the sliding limiting holes. The length of two ribs of the upper friction plate is the same as the length of the lower friction plate. The composite self-resetting hydraulic damper has the advantages of simple structure, multilevel energy consumption, much energy consumption, large deformation, and can effectively solve the problem of damage to the building caused by an earthquake.

Description

technical field [0001] The invention belongs to the field of anti-seismic energy consumption, in particular to a composite self-resetting hydraulic damper. Background technique [0002] With the frequent occurrence of earthquake disasters in recent years, new requirements have been put forward for the anti-seismic ability of buildings in the construction of construction projects. The traditional anti-seismic structure of buildings consumes earthquake energy through the deformation of the building's own components, which will cause permanent damage to the building's own structure. Sexual damage will have a greater impact on the safety of the building in the later use. By adding a damper component to the building structure, the component can be used to absorb most of the seismic energy, effectively reducing the damage to the building body structure caused by the earthquake, and playing an important role in improving the overall seismic performance of the building. Therefore u...
