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 invention provides a double-aluminum-alloy-plate assembly type buckling restrained brace. Core plates are fixed to the two sides of a steel i-beam through bolts by using upper channel steel, lowerchannel steel and middle channel steel; large overall bending rigidity of the brace can be provided, the requirement for the constraint ratio is easily met, the brace can quickly enter the plastic energy dissipation state when bearing a reciprocating load, and earthquake energy can be dissipated to a larger extent; the core plates are made of aluminum alloy so that the dead weight of the structure can be reduced to a certain extent. The structure is in an assembly type and is convenient to detach, damaged parts can be conveniently replaced after earthquakes, and economic benefits and the social benefits are outstanding.

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...
