Theory analysis research all shows which possesses than the more preferable energy dissipation capacity of conventional steel frames node.But with load and cycle-index
Increase, after the pressurized particularly pressurized surrender in beam-ends reduced beam section position and steel plate may be produced when correspondingly web is pressurized and is cut and be put down
There is a certain degree of rigidity, strength degradation in flexing unstable phenomenon outside face, node hysteresis loop.This edge of a wing may with web
The outer flexing unstability of the steel plain of generation, gently then affects the performance of node energy dissipation capacity, and the low week for reducing reduced beam section position is tired
It is the labor life-span, heavy then cause node premature degradation.Also the test having shows, as the edge of a wing that dog-bone joint weakens node district is cut
Face, causes girder steel out of plane stiffness to reduce, and easily produces the outer complete buckling of girder steel plane.
On the other hand, buckling restrained brace BRB is one kind by external constraint part constraint supporting core plate and limits which
The axially loaded component of compressive buckling, can give full play to hysteresis of the core board under circulation tension and compression effect under violent earthquake effect
Performance, reaches the purpose of dissipation seismic energy.If the upper and lower reduced beam section portion of dog-bone joint beam-ends can be limited by similar measure
After the pressurized particularly pressurized surrender in position and correspondence web is pressurized and issuable flat out-of-plane buckling unstability when being cut, and using about
The out of plane stiffness of bundle device prevents steel beam joint area lateral bucking, is beneficial to dog-bone joint energy-dissipating property and energy dissipation capacity
Stable performance.
For the problems referred to above, the present invention proposes a kind of buckling-restrained device of dog-bone joint beam-ends：In dog-bone joint beam
Hold, and arrange about in the upper and lower reduced beam section position correspondence web both sides of beam-ends
Beam channel-section steel, arranges filling plate between constraint cover plate and constraint channel-section steel, will constrain cover plate, constraint channel-section steel and filling by connecting bolt
The complete restraint device of plate connection composition.The restraint device can effectively limit pressurized being particularly in the upper and lower reduced beam section position of beam-ends and receive
After lateral deflection clothes and correspondence web is pressurized and by the outer amplitude flexing unstability that may occur of steel plain when cutting, preventing may generation
Reduced beam section position fatigue life reduce and connection stiffness, strength degradation, prevent node district girder steel occur plane outside integrally bend
It is bent, it is ensured that hysteresis loop is full, improves the lateral stability of column joints deformation ability, ductility and beam, gives full play to dog bone type section
The excellent energy-dissipating property of point.
