Song induction support, suitable for steel construction or concrete structure with buckling restrained brace.
Background technique
In steel construction or reinforced concrete structure use process, common support compression can generate buckling phenomenon, work as branch
After supportting compressive buckling, rigidity and bearing capacity are drastically reduced.Under earthquake or wind action, the internal force of support is being pressurized and tension two
Back and forth change under kind state.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, casing is set outside support, constrains the compressive buckling of support, constitute buckling restrained brace only core plate and other
Component connection, suffered load are all undertaken by core plate, and outer sleeve and packing material only constrain core plate compressive buckling, and core plate is made to exist
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
It, can be on the other hand with the energy dissipation capacity of metal damper to avoid the defect of common support tension and compression bearing capacity significant difference
" fuse " is served as in the structure, so that main structure is substantially in elastic range.Therefore, the application of buckling restrained brace,
Anti-seismic performance of traditional braced frame under middle shake and big shake can be improved comprehensively.But traditional buckling restrained brace is usually adopted
With steel and coagulation local soil type at restraining tube, it is high to lead to make precision prescribed, from great and difficulty of construction is big, to core cell sheet
Body promotes it and is very limited with use scope there are larger additional load.
