Energy-dissipating joint assembly and earthquake-resistant structure using the same

Abstract

The invention relates to an energy-dissipating joint assembly and an anti-seismic structure using the same. The energy-dissipating joint assembly includes: a joint plate having two joint sections and an energy-dissipating section, the two joint sections are used to join a structural body, the energy-dissipating section is located between the two joint sections, and The energy dissipation section has a plurality of slots, each of which has a length and a width; and a plurality of bolts, the steel plates in the energy dissipation area are provided with slots, and the slots are equipped with bolts, and the bolts are used to bind The steel plate is deformed outside the plane, and the bolts in the slots can slide on the plane of the steel plate. The two end regions of the energy dissipation section are firmly joined with the structural body. Each of the bolts has a head, and the outer diameter of each head is smaller than the length of each of the slots, but larger than the width of each of the slots. The invention can convert the external force acting on the structure body into more uniform tension and pressure in the energy dissipation area, so as to avoid stress concentration and destroy the structure body.

AI Technical Summary

Problems solved by technology

Cooperate with reference figure 1 and figure 2 , when the known steel bridge column (beam) structure 60 is subjected to the earthquake horizontal force, the maximum acting bending moment will be generated at the bottom of the steel bridge column 61, thereby causing the steel bridge column 61 to produce deflection deformation and local buckling, As a result, the steel bridge column 61 breaks, and the anchorage of the steel bridge column 61 is buried deep in the ground, so it is difficult to detect its damage after the earthquake

In addition, the steel bridge column 61 can only produce a traditional plastic hinge in mechanics under ideal conditions, so the earthquake resistance is also limited

[0004] In addition, the known cause of damage to building steel structures is often that the earthquake force will be concentrated in the beam-column joint area, so that the structure breaks or collapses

[0005] Since the damage of the above-mentioned structures may cause serious disasters and huge property losses, it is necessary to provide an innovative and progressive energy-dissipating joint component and a shock-resistant structure to solve the above-mentioned problems
