Replaceable assembled type energy dissipating and vibration damping joint provided with self resetting function

Abstract

The invention discloses a replaceable assembled type energy dissipating and vibration damping joint provided with the self resetting function. The replaceable assembled type energy dissipating and vibration damping joint comprises a joint energy dissipating and resetting function connecting plate, a self resetting spring, energy dissipating soft steel, high strength anchor bolts, an assembled typereserved hole duct, a pre-stressed bar and a joint core area. The joint energy dissipating and resetting function connecting plate is connected with the joint core area and other prefabricated assembled type members by using the assembled type reserved hole duct through the high strength anchor bolts and the pre-stressed bar in an assembled mode. The edge of a flange plate of the energy dissipating and resetting function connecting plate is provided with a plurality of pre-pressing self-resetting springs with the same tension and compression stiffness according to resetting need. The energy dissipating soft steel is in assembled connection with the joint energy dissipating and resetting function connecting plate. The replaceable assembled type energy dissipating and vibration damping joint can be used as an independent system to replace the advantages of plastic hinged areas of traditional assembled beams, columns and piles, self resetting can be achieved during structural micro vibrating (shaking), and the replaceable (restoring) function is achieved effectively when post-vibrating (post-shaking) damage is generated.

Description

technical field [0001] The invention relates to an assembled energy-dissipating and vibration-reducing node for an assembled structure with replaceable, self-resetting and energy-dissipating and vibration-reducing (vibration) functions, belonging to the field of engineering vibration control. Background technique [0002] In recent years, with the development of social economy, the level of urbanization and the improvement of people's living standards, people are concerned about the safety of buildings and bridge structures under the action of multiple disasters, environmental pollution and energy consumption during construction and use, as well as economy and durability. The requirements are getting higher and higher. Prefabricated structures and recoverable structures have the advantages of convenient construction, short construction period, low energy consumption, and easy repair (replacement). Therefore, prefabricated structures and recoverable functional structures are ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of poor energy dissipation and vibration reduction ability of traditional assembled nodes, no self-resetting function, poor replaceable function, which will significantly change the structural dynamic energy consumption plastic hinge area, etc., the present invention proposes a soft steel joint with energy dissipation , can replace the beam-column plastic hinge area, and is equipped with a self-resetting spring, a replaceable assembled energy-dissipating and vibration-reducing node with self-resetting function connected by high-strength anchor bolts or prestressed steel strands
