Description
Technical field
The utility model relates to a kind of supporting member, is specifically related to a kind of supporting member of realizing energy-dissipating and shock-absorbing control, particularly a kind of collaborative power consumption curvature-prevention support component.
Background technology
In recent years, violent earthquake frequently took place in the world wide, and Given this, scholars propose definition megaseisms notion outside level is set up defences in big shake, middle shake, little shake, surmount the extreme seismic load of big shake on its expression amplitude Characteristics, try hard to realize megaseisms safety.Therefore, for the important building of function, in the traditional design theory, introduce the building structure aseismatic fortification measure under big shake of super expection even the megaseisms situation, have important practical significance and safe value, also perfect to a certain extent Aseismic Design Theory framework based on performance.
As under medium and small shake, having enough rigidity, the good a kind of novel supporting member of energy-dissipating property under big shake, anti-flexing supports (Buckling-restrained brace, the normal BRB of abbreviation supports) can satisfy multistage specific requirement of setting up defences, along with the engineering application and development, the anti-flexing supported that has also occurred various ways in succession, with regard to the anti-flexing supporting form that present institute proposes and adopts, its power consumption design under big shake is a key character with the total cross-section surrender often, this can cause some problem, as: the strong elastic-plastic deformation that is supported on big shake under of power consumption can produce bigger remaining displacement, causes resetting after the shake and changing comparatively difficult; In view of present design concept, the strong elastic-plastic deformation performance that anti-flexing is supported under the big shake often can not satisfy power consumption and the safety requirements that surpasses under big shake of expection even the megaseisms; If consider to ensure super power consumption and work safety of expecting that the down anti-flexing of big shake supports, can cause the increase of material and manufacturing cost on the one hand, can cause big shake in fact still to utilize rigidity characteristic that anti-flexing supports down but not the elastoplasticity energy dissipation capacity on the other hand, be equivalent to improve the design level, this is not the effective way of dealing with problems.Therefore; be necessary that anti-flexing support is transformed to existing tradition; the anti-flexing supporting form of a kind of novel energy-consumption is proposed; make it can under small earthquakes, possess enough rigidity; under big shake, have enough energy dissipation capacities, simultaneously, can also under big shake of super expection even megaseisms, have lasting energy dissipation capacity; and formation is supported in power consumption necessarily protected, prevent its rupture failure.Based on this, be necessary to research and develop a kind of novel novel curvature-prevention support component that oneself resets of realizing with big shake defencive function.
The utility model content
In order to remedy the defective of prior art; the utility model patent provides a kind of collaborative power consumption curvature-prevention support component with big shake defencive function; can under small earthquakes, possess enough rigidity; under big shake, have enough energy dissipation capacities; simultaneously; can also under big shake of super expection even megaseisms, have lasting energy dissipation capacity; and formation is supported in power consumption necessarily protected; prevent its rupture failure; and have the earthquake centre and the shake after from reset function; can effectively strengthen and prevent that flexing is supported on applicability and the safety under the uncertain macroseism, more has practical value.
