Description
Technical field
The present invention relates to a kind of energy-dissipated brace component, and in particular to a kind of modularization assembling buckling restrained brace
Component.
Background technology
Buckling restrained brace is also known as undonded prestressed concrete, is a kind of novel earthquake-proof dissipative member of superior performance, it is a kind of by
The energy-consumption supporting member of surrender is drawn and be attained by the case of being pressurized, traditional support is improved and lacking for flexing occurs when being pressurized
Point, improves the anti-seismic performance of structure.
Buckling restrained brace (abbreviation BRB) most starts to develop and progressively develop into early in 20th century 70 to the nineties in Japan
It is ripe, promote in Japan, the U.S. and Taiwan and generally use later.1971, Yoshino etc. cut built-in steel plate
Power wall has carried out hysteretic test research, and steel plate is the cross bar of X-shaped arranged crosswise, and test specimen is divided to two groups.In identical loading level
Under, stay one group of 15mm gaps to show more preferable ductility than gapless one group between steel plate and concrete, have fuller
Full hysteresis loop.
Wakabayashi etc. has carried out a series of examination to the steel plate support between being clipped in two sides precast rc slab
Research is tested, wherein unidirectional load test examines the rigidity and intensity requirement of concrete slab, pull compares different nothings
The performance of binding material, and assembly test has then investigated the hysteretic energy performance of structure.
Fujimoto etc. has carried out theoretical and experimental study to BRB of the constraint element for back-up sand slurry in rectangular steel pipe, is protecting
Hold kernel unit sectional dimension it is constant under conditions of by varying the outside diameter and wall thickness of constraint element simulate different constraint bars
Part, investigates the stress performance of support, has obtained the rigidity and Strength Design Criteria of steel sleeve.Start after into the nineties in Japan
After a large amount of popularizations, particularly Kobe earthquake, buckling restrained brace is used in Japanese a large amount of new constructions and reinforcing engineering.
The U.S. is after it experienced 1994 Nian Bei ridges earthquakes, the last century 90's end buckling-restrained energy-dissipation and its structure
The research of system and apply and start to be paid attention in the U.S..
Many scholars expand research to the fatigue behaviour of BRB and the anti-seismic performance of BRB after 2000.2002,
Yamaguchi etc. is to setting the steel frame of common support and buckling-restrained energy-dissipation to carry out the shaketalle test pair of full size cun
Than investigating support and the collective effect of frame.
Research of the China to buckling restrained brace begins one's study after 2000 than later, mainly continues to use the U.S. and Japan
Structural form.There are Tongji University, Tsinghua University, Xi'an University of Architecture and Technology etc. in main research institution.
Buckling restrained brace tensile and compressive property is suitable, the full stabilization of hysteresis loop, it can not only be used as structural elements, after surrender
And a kind of damper of function admirable, can largely dissipate inputting seismic energy, and by the damage concentration of structure in buckling-restrained
Itself is supported, protects agent structure, reduces seismic structural response.At present, buckling restrained brace structural form both domestic and external
It can be generally divided into two classes：(1) clean steel type buckling restrained brace；(2) the buckling-restrained branch using concrete filled steel tube as constraint element
Support.
Steel are usually used in buckling restrained brace of the prior art and concrete (the grouting bed of material) is used as main material
Make, wherein generally according to the size of member stress by the way of steel plate welding, such way has following several for core part
A drawback：
(1) need to use steel plate thickness specification more when the stress tonnage specification of component is more, when causing practical application
The steel plate of a large amount of specifications is purchased, causing the utilization rate of steel plate reduces；
(2) the larger steel plate of thickness can be used when the stress of component is larger, to material when the thickness of steel plate is bigger
The quality of buying and welding can cause large effect；
(3) in same project, the workload and complexity processed when product specification is more are larger, in process
Easily error, standardization level is than relatively low.
