Description
Technical field
The invention belongs to building structure technology field, more particularly to a kind of sleeve pipe with oblique pineapple type induction unit
Flexing induction support, 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
The problem of energy difference, in the outside setting sleeve pipe of support, the compressive buckling of constraint support constitutes buckling-restrained buckling restrained brace only core
Plate is connected with other components, and suffered load is all undertaken by core plate, and outer sleeve and packing material only constrain core plate compressive buckling,
Core plate is set to enter surrender in tension and by pressure, thus, the Hysteresis Behavior of buckling restrained brace is excellent.Buckling restrained brace
On the one hand the defect of common support tension and compression bearing capacity significant difference can be avoided, on the other hand the power consumption energy with metal damper
Power, can serve as " fuse " so that agent structure is substantially in elastic range in the structure.Therefore, buckling restrained brace
Application, can comprehensively improve anti-seismic performance of traditional support frame under middle shake and big shake.
Applicant proposed a kind of end on June 1st, 2016 has the flexing control of duplex pyramid type power consumption unit
Support (Application No. 201610380805.2) and a kind of end have the flexing control support of staggeredly pyramid power consumption unit
