During steel construction or reinforced concrete structure use, common support is pressurized to produce flexing phenomenon, when
After support compressive buckling, rigidity and bearing capacity are drastically reduced.Under earthquake or wind action, the internal force of support is in pressurized 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 of support and rigidity are close to
Zero.Thus common support Hysteresis Behavior under course under cyclic loading is poor.For solving common support compressive buckling and hysteresis
Can difference problem, support outside sleeve pipe is set, constrain the compressive buckling for supporting, constitute buckling restrained brace only central layer and other
Component connects, and suffered load is all undertaken by central layer, and outer sleeve and packing material only constrain central layer compressive buckling, so that central layer is existed
Tension and all being entered by pressure is surrendered, thus, the Hysteresis Behavior of buckling restrained brace is excellent.Buckling restrained brace on the one hand can
So that the defect of common support tension and compression bearing capacity significant difference is avoided, on the other hand there is the energy dissipation capacity of metal damper, permissible
Serve as " fuse " in the structure so that agent structure is substantially in elastic range.Therefore, the application of buckling restrained brace,
Traditional support frame anti-seismic performance under middle shake and big shake is improved comprehensively can.But traditional buckling restrained brace is generally adopted
With steel and the restraining tube of concrete composition, cause to make precision prescribed height, big from great and difficulty of construction, to core cell sheet
There is larger additional load in body so as to promote and range is very limited.
