Friction energy consumption type node connection device for self-centering pier column structure

InactiveCN101936043AImprovement of local pressure problemsImprove performanceShock proofingPile capResidual deformation
The invention relates to a friction energy consumption type node connection device for a self-centering pier column structure, which is a device used for connecting a bridge pier or a frame column with a pile cap (a foundation), so as to improve the energy consumption of the pier column structure under the action of earthquake and eliminate or reduce the residual deformation and the injuries of the structure. The device comprises a pier column strengthening steel plate, a foundation pre-embedded steel plate, an angle steel, a friction bolt, a friction plate, unbonded prestressed tendons, an anchor bolt and the like. The device can connect a concrete pier column and the foundation into a whole through the unbonded prestressed tendons which are vertically arranged. When the earthquake strength achieves a certain degree, the pier column-foundation contact surface is open, and the pier column can produce a certain rotation relative to the foundation. A friction device can dissipate earthquake energy through friction at this time, and the prestress provided by the prestressed tendons can recover the structure to the initial position after the earthquake. A pre-embedded part at the end part of the pier column is used for improving the local bearing pressure of the concrete when the pier column rotates relatively.
