Variable stiffness and energy dissipation type fabricated transverse connection structure

Abstract

The invention relates to a variable stiffness and energy dissipation type fabricated transverse connection structure and an installation method thereof, and belongs to the technical field of building structure earthquake resistance. The variable stiffness and energy dissipation type fabricated transverse connection structure includes an energy dissipation zone and a lifting zone, the energy dissipation zone uses the deformation energy dissipation of soft steel or stainless steel, the lifting zone uses the deformation energy dissipation of screws of common bolts, and threshold control is realized by setting the size of bolt holes on steel plates of the lifting zone. When small earthquakes and moderate earthquakes occur, end plates connected with structural members move relatively with the relative movement of the structural members, at the moment, energy dissipation steel plates dissipate energy through deformation, the first stage of energy dissipation is achieved; and When large earthquakes occur, the end plates move relatively and exceeds the threshold, screws in the lifting zone are in contact with bolt holes on variable cross-sections and starts to deform and dissipate energy, at the moment, the screws in the lifting zone and the steel plates in the energy dissipation zone commonly deform and dissipate energy, the second stage of the energy dissipation is achieved, jumping again can be achieved after bearing capacity reaches the peak value, after the earthquakes, components can be replaced or a whole damper can be replaced according to the actual damage of the damper, bolted connection can be easily replaced and disassembled, and the concept of sustainable development is met.

Description

technical field [0001] The invention relates to a variable-rigidity energy-dissipating assembled transverse connection structure and an installation method thereof, and belongs to the field of anti-seismic technology of building structures. It can be applied to prefabricated structures in earthquake-prone areas. Background technique [0002] With the continuous progress of the construction industry, prefabricated assembly is an important construction method to realize the transformation and development of the construction industry. The cost of prefabricated buildings is low, the construction is fast and convenient, and the waste of resources and environmental pollution caused by it is small. It has been vigorously promoted by the country. And because of its good bearing capacity and deformation capacity, it is widely used in high-rise and super high-rise buildings. However, the joints and joints of prefabricated buildings are relatively weaker than those of poured buildings...
