Description
Technical field
The invention belongs to building structure technology field, more particularly to a kind of end has change length bilayer inner concave shape induction
The flexing induction support of unit, it is adaptable to steel construction or concrete structure with buckling restrained brace.
Background technology
During steel construction or reinforced concrete structure use, common support is pressurized and can produce flexing phenomenon, works as branch
After support compressive buckling, rigidity and bearing capacity are drastically reduced.Under earthquake or wind action, the internal force of support is in compression and tension two
Back and forth change under the state of kind.When support gradually fades to tension state by the state of buckling, the internal force and rigidity of support are close to
Zero.Thus common support Hysteresis Behavior under course under cyclic loading is poor.To solve common support compressive buckling and hysteresis
Can difference problem, in the outside compressive buckling for setting sleeve pipe, constraining support of support, constitute buckling restrained brace only core plate and other
Component is connected, and suffered load is all undertaken by core plate, and outer sleeve and packing material only constrain core plate compressive buckling, core plate is existed
Tension and by pressure can enter surrender, thus, the Hysteresis Behavior of buckling restrained brace is excellent.Buckling restrained brace on the one hand can
To avoid the defect of common support tension and compression bearing capacity significant difference, the on the other hand energy dissipation capacity with metal damper can be with
Serve as in the structure " fuse " so that agent structure is substantially in elastic range.Therefore, the application of buckling restrained brace,
Anti-seismic performance of traditional support frame under middle shake and big shake can comprehensively be improved.But traditional buckling restrained brace is generally adopted
With steel and coagulation local soil type into restraining tube, it is high to cause to make precision prescribed, big from great and difficulty of construction, to core cell sheet
There is larger additional load in body, it is promoted and is very limited using scope.
