An easily replaceable metal damper and beam-to-column connection node for the top of a bent corbel

Abstract

The invention discloses an easily-changed metal damper and a beam-column connection node for a bracket column top of a bent frame. The damper consists of upper and lower end plates, a middle lower endplate, a supporting plate, a soft steel energy-consuming assembly, a graduation ruler, a graduation ruler support, vertical and horizontal strip-shaped supporting steel plates, stiffening blocks anda shear energy-consuming assembly. The shearing energy-consuming assembly includes a rubber block, a U-shaped steel plate, a slidable single-sided wavy plate, a wavy force transfer plate, a square steel tube, an upper-portion round steel tube, a lower-portion round steel tube, a spring, a connecting plate and angle steel. The soft steel energy-consuming assembly includes a wavy soft steel plate, alower force transfer rod and a force transfer rod support. The supporting steel plates and the middle lower end plate are connected and the upper and lower force transfer rods and the force transferrod support are connected both by friction type high-strength bolts, the connecting plate and the angle steel and the U-shaped steel plate are connected by common bolts, and the residual members are welded. The energy-consuming mechanism of the easily-changed metal damper is more effective, has better vibration damping and isolation effects, and the normal functions of the structure can be quicklyrestored by quickly replacing the damper after an earthquake.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, and mainly relates to an easily replaceable metal damper and a beam-column connecting node for the top of a bent corbel. Background technique [0002] Traditional buildings mainly rely on the deformation of the structure itself to absorb earthquake energy, and many major components are difficult to repair after damage. With the continuous advancement of anti-seismic theory, technology and methods and the development and application of more high-performance materials, people have higher and higher requirements for the anti-seismic performance of structures. After the earthquake, the loss of the whole society will be minimized. [0003] Among the several methods to realize the recoverable functional structure, the most operable is the replaceable structure. Replaceable structural components are set in the structure, and the damage of the structure is mainly concent...

AI Technical Summary

Problems solved by technology

In order to reduce the brittle failure of the beam-column joints of the bent structure under the action of earthquakes, and ensure that the frame beam-column can still maintain good ductility after the earthquake, so as to achieve the effect of dissipating seismic energy, the general method is to Adding a damper, but the existing damper has poor energy dissipation capacity, and the effect of shock absorption and isolation is not obvious, so it is necessary to propose a new type of damper
