The anti-buckling support of formula.
Background technology
After experiencing repeatedly actual seismic inspection, curvature-prevention support component gradually obtains research worker and engineering design
The accreditation of personnel, particularly in Japan, the U.S. and China Taiwan, it is non-that the research work of anti-buckling support has been carried out
The most deeply, its engineer applied is the most quite varied.Comparatively speaking, the correlational study of domestic anti-buckling support and application starting are relatively
In evening, after Wenchuan earthquake, anti-buckling support has obtained quick popularization and application, at present, in addition to newly-built structure field, in engineering
Field of structural seismic reinforcement, the application of anti-buckling support is the most common.
Curvature-prevention support component has the anti-side rigidity of common support and the double effects of dissipative member concurrently, reasonable in design
Curvature-prevention support component will not occur compressive buckling to destroy when pressurized, and all can realize surrender power consumption when tension and pressurized,
There is good energy-dissipating and shock-absorbing performance, be widely used in field of engineering technology.Typical curvature-prevention support component is mainly by consuming
Energy inner core, confining part and non-cohesive material therebetween or gap are constituted.Wherein, energy consumption inner core is solely subjected to axle power,
Only producing axial deformation, confining part then prevents inner core pressurized lateral buckling by its bending rigidity and anti-bending bearing capacity.
At present, curvature-prevention support component conventional on market, its restraining tube form mainly has three types, is armored concrete respectively
Constraint, steel concrete combination constraint and all steel constraint.
The reinforcing bar solidifying soil anti-buckling support of restraining tube type, component own wt is relatively big, and designs with the connection of peripheral structure
Complex, more difficulty of simultaneously constructing, application is less at present.All steel constraint steel using amount is higher, and processing technology requires height, causes
Support cost higher, it is difficult to spread.Traditional steel concrete restricted type supports, general employing steel pipe type closure member
Concrete filled, energy consumption inner core is placed in concrete, and keeps certain gap with concrete, to ensure the freedom of energy consumption inner core
Dilatation, and in practical operation, pouring of concrete is difficult to accurately control, therefore, between energy consumption inner core and concrete between
Gap precision is difficult to meet design requirement.
Utility model content
