Problems solved by technology

[0006] According to the current research status of buckling-restrained bracing, there are mainly the following problems: (1) the self-weight of the bracing is too large, which causes a greater burden on the beam and column, and it is difficult to process; (2) the core plate is easily damaged at the end of the stiffener after the earthquake, so (3) The initial stiffness and yield point of the aluminum alloy are too low, so it is easy to start working after a small earthquake, and the structure itself can completely resist the vibration at this time; (4) The core material is not easy to replace after the earthquake, and the support cannot reuse

Abstract

The bi-aluminum alloy plate assembly-type buckling-constrained support described in the present invention uses upper and lower channel steels and middle I-steel to fix the core plate on both sides of the I-steel through bolts, which can provide a larger overall bending stiffness of the support and is easier to meet Constraint ratio requirements, the support can quickly enter the plastic energy dissipation state when it is subjected to reciprocating loads, and consume seismic energy to a greater extent, and the core plate is made of aluminum alloy, which can reduce the structural weight to a certain extent. , easy to disassemble, easy to replace damaged parts after the earthquake, outstanding economic and social benefits.

Description

technical field [0001] The invention is mainly used in the field of civil engineering, and is very effective in anti-seismic and reinforcement of buildings, and specifically relates to a double aluminum alloy plate assembled buckling restraint support. Background technique [0002] As a common natural disaster, earthquakes bring great disaster and suffering to human beings every time they occur. Therefore, it is of great significance to study economical and effective anti-seismic measures. The traditional anti-seismic method of structures is to resist earthquake action by increasing the strength and stiffness of the structure itself, and at the same time use the ductility of the structure, that is, the plastic deformation of the structure itself, to consume the energy input by the earthquake. This passive anti-seismic countermeasure is not advisable. Since Japanese scholars first proposed and applied buckling-restrained braces in the last century, earthquake damage has been...
