Rotational friction energy dissipation type self-resetting fabricated beam-column joint
The invention discloses a rotational friction energy dissipation type self-resetting fabricated beam-column joint. The rotational friction energy dissipation type self-resetting fabricated beam-column joint comprises a prefabricated column, an unbonded prestressed tendon, a prefabricated column upper sleeve plate and a prefabricated beam sleeve plate, the side face of the prefabricated column is fixedly connected with a prefabricated beam, the prefabricated column upper sleeve plate is connected into the prefabricated column in an embedded mode, and the interior of the prefabricated beam is connected with the prefabricated beam sleeve plate in an embedded mode. According to the rotational friction energy dissipation type self-resetting fabricated beam-column joint, the problem that a traditional fabricated concrete beam-column joint is poor in anti-seismic effect is well solved by arranging unbonded prestressed tendons and installing rotational friction dampers on the fabricated concrete beam-column joint, due to the fact that the concrete beam-column joint is in dry connection with the unbonded prestressed tendons and the rotational friction dampers, the purposes of structure self-resetting and earthquake energy consumption can be achieved during application, the earthquake resistance of the structure is further guaranteed, the earthquake resistance effect of the beam-column joint applying the self-resetting damper is greatly improved, and the practicability is high.
本发明公开了一种转动摩擦耗能型自复位装配式梁柱节点，包括预制柱、无粘结预应力筋、预制柱上部套板以及预制梁套板，所述预制柱的侧面固定连接预制梁，所述预制柱的内部通过镶嵌的方式连接预制柱上部套板，所述预制梁的内部通过镶嵌的方式连接预制梁套板。该一种转动摩擦耗能型自复位装配式梁柱节点，通过对装配式混凝土梁柱节点配置无粘结预应力筋以及安装转动摩擦阻尼器，较好的解决了传统装配式混凝土梁柱节点抗震效果较差的问题，由于混凝土梁柱节点和无粘结预应力筋、转动摩擦阻尼器之间采用的是干连接的方式，在应用时可以达到结构自复位及消耗地震能的目的，从而进一步的保证结构的抗震性能，大大提高了应用该自复位阻尼器的梁柱节点的抗震效果，实用性较强。
