Description
Technical field
The utility model relates to engineering structures energy-dissipating and shock-absorbing field, particularly a kind of super-elasticity Self-resetting energy-dissipating device.
Background technology
Metal species energy-consuming shock absorber is installed in engineering structures and has been proved to be a kind of very effective seismic fortification method to the earthquake alleviating structure, but permanent set is larger after current most metal species energy-consuming shock absorber shakes, need to carry out repairing or changing after shake, cause the life-cycle use cost of structure to rise.
Therefore, develop that a kind of energy dissipation capacity is strong and after shake, permanent set is little metal species energy-consuming shock absorber just seems both urgent and meaningful especially.
Summary of the invention
In order to overcome the larger weak point of permanent set after macroseism that at present existing most metal species energy-consuming shock absorber exists, the utility model provides the super-elasticity Self-resetting energy-dissipating device that permanent set after a kind of macroseism is less.
The technical scheme that the utility model adopts is a kind of super-elasticity Self-resetting energy-dissipating device, it is primarily of U-type groove, inside stretch steel plate, mild-steel energy-consumption plate and SMA Tendons composition, U-type groove is made up of two blocks of parallel steel plate steel plates vertical with a piece, inside stretch steel plate and stretch into the middle part of U-type groove and parallel to each other with two pieces of parallel steel plates of U-type groove, the clear distance inside stretched between steel plate end and the vertical steel plate of U-type groove is not less than 5 centimetres, mild-steel energy-consumption plate is arranged on the parallel steel plate of U-type groove and interiorly stretches between steel plate, SMA Tendons crossed-symmetrical is anchored at U-type groove and interior both sides of stretching steel plate.
Described mild-steel energy-consumption plate is the rectangular steel plates that X-shaped steel plate or centre have rhombus hole.
Described mild-steel energy-consumption plate is made up of the steel plate of yield strength lower than 235MPa.
Described SMA Tendons should be stretched to 20% ~ 50% of its recoverable strain in advance.
Described super-elasticity Self-resetting energy-dissipating device is arranged on the position that structure produces larger relative deformation, and when macroseism by mild-steel energy-consumption plate and SMA Tendons dissipation seismic energy, after macroseism, SMA Tendons can make mild-steel energy-consumption plate Self-resetting.
The utility model has following remarkable advantage:
(1) energy dissipation capacity is strong.The utility model is by mild-steel energy-consumption plate and SMA Tendons combination power consumption, and effectively can dissipate when macroseism seismic energy.
(2) after shake, permanent set is little.The utility model can provide self-resetting capability to super-elasticity Self-resetting energy-dissipating device by SMA Tendons, effectively reduces the rear permanent set of its shake.
The utility model can be used for needing carrying out in the building structure that emphasis provides fortification against earthquakes, and not only can effectively dissipate Seismic input structural energy, and have good self-resetting capability, after shake, permanent set is little, easy to process, cost is reasonable, has a good application prospect.

1-U type groove; Steel plate is stretched in 2-; 3-mild-steel energy-consumption plate; 4-SMA Tendons.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figure 1 and 2, the utility model is a kind of super-elasticity Self-resetting energy-dissipating device, it is primarily of U-type groove 1, inside stretch steel plate 2, mild-steel energy-consumption plate 3 and SMA Tendons 4 form, U-type groove 1 is made up of two blocks of parallel steel plate steel plates vertical with a piece, inside stretch steel plate 2 and stretch into the middle part of U-type groove 1 and parallel to each other with two pieces of parallel steel plates of U-type groove 1, the clear distance inside stretched between steel plate 2 end and the vertical steel plate of U-type groove 1 is not less than 5 centimetres, mild-steel energy-consumption plate 3 is arranged on the parallel steel plate of U-type groove 1 and interiorly stretches between steel plate 2, SMA Tendons 4 crossed-symmetrical is anchored at U-type groove 1 and interior both sides of stretching steel plate 2.
Described mild-steel energy-consumption plate 3 is the rectangular steel plates that X-shaped steel plate or centre have rhombus hole.
Described mild-steel energy-consumption plate 3 is made up of the steel plate of yield strength lower than 235MPa.
Described SMA Tendons 4 should be stretched to 20% ~ 50% of its recoverable strain in advance.
Described super-elasticity Self-resetting energy-dissipating device is arranged on the position that structure produces larger relative deformation, to be dissipated seismic energy by mild-steel energy-consumption plate 3 and SMA Tendons 4 when macroseism, after macroseism, SMA Tendons 4 can make mild-steel energy-consumption plate 3 Self-resetting.
Specifically in the present embodiment, mild-steel energy-consumption plate 3 is X-shaped steel plate, and yield strength is 160MPa, and SMA Tendons 4 is stretched to 30% of its recoverable strain in advance.
The utility model can not only effectively dissipate Seismic input structural energy, and has good self-resetting capability, and after shake, permanent set is little.The utility model clear concept, convenient processing and manufacture, cost is reasonable, will be widely used in needing carrying out in building structure that emphasis provides fortification against earthquakes.
