Background technology
At present, Structural Energy Dissipation cushion technique is becoming the focus of field of civil engineering disaster reduction and prevention.Architectural energy consumption damping utilizes principle of energy balance, reduces the destructiveness of structure in earthquake.Seismic input structural energy comprises: the power consumption of (1) structure kinetic energy, (2) structural damage, (3) structural elasticity potential energy, (4) viscous damping power consumption etc.Structural damage power consumption is more, and structural damage degree is more serious; Structure kinetic energy and elastic potential energy start to be zero, after earthquake terminates, and when structure stops rocking, it is still zero, does not participate in dissipation inputting seismic energy.Therefore, want to reduce structural damage power consumption, just can only increase the viscous damping power consumption of structure.For increasing viscous damping power consumption, can be structure and adding energy-consumption shock-absorption device, metal energy-dissipating device is just one wherein, and other type comprises viscoplasticity or oil pressure viscous damper etc.
The invention belongs to a kind of metal energy-dissipation damper, existing shearing-type metal damper Energy Dissipation Mechanism mainly contains two kinds: (1) is by the inplane shear distortion power consumption of steel plate; (2) by the out-of-plane bending distortion power consumption of steel plate.
The first shearing type damper yield displacement is less, but ductility and ultimate deformation ability poor, when it is subject to horizontal shear effect, easily outside face, there is flexing unstable failure, thus stress there occurs change, it can play a role in malformation getting up early, but easily destroys again when displacement structure is larger.The second shearing type damper ductility and extreme displacement are comparatively large, but yield displacement is also comparatively large, and it is relatively late that it plays power consumption effect.
Destroy in order to avoid shear buckling occurs inplane shear distortion energy-consumption damper outside face, method conventional is at present at steel plate surface external welding ribbed stiffener, but this structure and processing method can cause welds residual thermal stress and causes damage to Wasted-energy steel plate, have a strong impact on its low cycle fatigue property, the energy dissipation capacity of steel can not be made full use of.
Utility model content
Technical problem to be solved in the utility model is exactly for existing shearing-type metal damper above shortcomings, and provide a kind of channel-section steel to retrain shearing type damper, it can provide larger additional damping, reduces geological process, protection agent structure.
For achieving the above object and other relevant objects, the utility model provides a kind of channel-section steel to retrain shearing type damper, at least comprise shear energy dissipation steel plate in one piece of square face, two channel-section steel confining parts, two outer shroudings of channel-section steel, top board and base plate and two pieces of side stiffeners, two opposing settings of channel-section steel confining part, the outer shrouding of described channel-section steel covers the opening surface of channel-section steel confining part, inplane shear Wasted-energy steel plate is clamped between two channel-section steel confining parts, the web of described channel-section steel confining part with inplane shear Wasted-energy steel plate wear split bolt be connected, four sides of inplane shear Wasted-energy steel plate vertically connect top board respectively, base plate and two side stiffeners.
Further, the outer shrouding of described channel-section steel is fixedly welded on two wing plates of described channel-section steel confining part.
Further, on the web of described channel-section steel confining part and inplane shear Wasted-energy steel plate, correspondence arranges multiple bar hole, and described multiple bar hole is symmetrical around the axis of inplane shear Wasted-energy steel plate equidistantly to be arranged.
By above technical scheme, the utility model has following technique effect compared to prior art: the utility model greatly improves the ability of building structure opposing horizontal earthquake action, improves the anti-seismic performance of structure; Utilize channel-section steel standard component as central layer out of plane constraint unit, can prevent from being cut central layer out-of-plane buckling, thus ensure that its pure shear stress; Avoid the welding sequence on central layer, improve the low cycle fatigue property of Wasted-energy steel plate, ensure that its inplane shear power consumption stress; Adopt channel-section steel standard element simultaneously, draw materials easily, processing capacity is little, considerably reducing processing cost, is a kind of energy-dissipating device with good promotion prospect.
