Abstract
A C-shaped steel bomb plastic damper relates to the bridge technology, in particular to an elastic-plastic steel damper for a bridge. The damper is provided with a curved beam; and stress points are arranged at two ends of the curved beam. The utility model has the advantages of simple structure, easy production and lower cost, and simultaneously has good mechanical property and earthquake resistant performance.
Description
Technical field
The utility model relates to bridge technology, particularly the elastoplasticity damper used of bridge.
Background technology
The elastoplasticity damper utilizes the theoretical development of energy-dissipating and shock-absorbing; It possesses good antidetonation shock attenuation function, has avoided the damage of bridge when earthquake; The elastoplasticity damping supporting seat combines ball shaped steel bearing and damper, the effect of usual performance ball shaped steel bearing, the effect of performance elastoplasticity damper can effectively consume seismic forces during earthquake, has improved the reliability and the durability of bridge greatly with minimum engineering input.
The elastoplasticity damper is a kind of of passive energy dissipation device in the structure Passive Control, have stable hysteretic characteristic, good low-Cycle Fatigue Characteristics, be not subjected to the advantages such as influence of environment temperature, when earthquake or wind shake, energy by the distortion of steel generation plastic yielding hysteresis in the dissipation input structure, thereby reach the purpose of vibration damping, make it very wide in actual application in engineering prospect.
The utility model content
Technical problem to be solved in the utility model is, a kind of elastoplasticity damper is provided, and has simple structure and good damping effect.
The technical scheme that the utility model solve the technical problem employing is that C shaped steel elastoplasticity damper has a curved beam, only at the two ends of curved beam stress point is set.
Specifically, described curved beam is the arc beam, is provided with connecting hole at the curved beam two ends.
The beneficial effects of the utility model are, and are simple in structure, are easy to produce, and cost is lower, has good mechanical property and damping performance simultaneously.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is a user mode schematic diagram of the present utility model.Wherein a, b are the lateral view of both direction, and c is a schematic perspective view.
The specific embodiment
Referring to Fig. 1.
Present embodiment has a curved beam, only at the two ends of curved beam stress point is set, and described stress point is and the application point of outside generation power conduction, in other words, is connected with outside at stress point.
Be out of shape the displacement generation retardation of the stress of generation to the curved beam end by curved beam.Offer circular connecting hole at the two ends of curved beam.Connecting hole is a through hole, is convenient to connecting pin and installs.
A kind of user mode schematic diagram such as Fig. 2 of present embodiment.4 groups of C shaped steel elastoplasticity dampers are installed on the support, every group of two dampers; Anchor plate 11 and the column 11,12,13,14,15,16 that is attached thereto constitute first structural group ( column 26,27 lays respectively at the both sides of column 25), anchor plate 21 and the column 22,23,24,25,26,27 that is attached thereto constitute first structural group ( column 23,24 lays respectively at the both sides of column 22), in 4 groups of dampers, the two ends of each damper are connected respectively on the column of two corresponding structural group.The anchor plate at support two ends is fixedly connected on respectively on bridge and the bridge pier, because the effect of each C shaped steel elastoplasticity damper, to the displacement movement of bridge with respect to bridge pier, i.e. displacement between two structural group produces retardation.
In the precedent, the two ends of C shaped steel elastoplasticity damper are provided with connecting hole, adopt pin to be connected with column, in fact also can adopt other connected modes, and anchor plate also is a kind of embodiment, and damper or column can be installed on the bridge by other modes.As long as adopt the arc curved beam, all belong to interest field of the present utility model.
The material of present embodiment elastoplasticity steel adopts Unite States Standard ASTM A516.70 grade pressure vessels steel plate, and its chemical composition and mechanical performance should meet related request; Or the number of adopting international standards is the SA516Gr.70 steel among the ASME SA-20/SA-20M, and its chemical composition and mechanical performance should meet related request.The pin that connects elastoplasticity steel and other part adopts 40Cr, and the chemical composition of material and mechanical performance should meet the requirement of GB/T 3077-1999.The part that damper is connected with bridge (beam) pier adopts Q345B low-alloy high-strength hot rolled steel plate or forging, and its material property should meet the requirement of GB/T 1591.
