Combined energy dissipation type beam-column joint device with self-recovery characteristic
The invention discloses a combined energy dissipation type beam-column joint device with a self-recovery characteristic. The combined energy dissipation type beam-column joint device comprises a concrete column, a concrete beam, a variable friction energy dissipation device and a shear steel plate energy dissipation device, wherein the variable friction energy dissipation device and the shear steel plate energy dissipation device are used for connecting the concrete column and the concrete beam; the variable friction energy dissipation device comprises a U-shaped inner friction connecting steel plate, a double-U-shaped middle friction connecting steel plate and a plate-shaped outer friction connecting steel plate. The inner friction connecting steel plate is fixed at the lower end of the concrete column, the upper end and the lower end of the middle friction connecting steel plate are both of a U-shaped structure, the U-shaped structure at the lower end is fixed on the concrete beam, and the inner friction connecting steel plate is correspondingly fixed in the U-shaped structure at the upper end of the middle friction connecting steel plate. The device is simple in form, convenient to install, good in anti-seismic performance, stable, reliable and very high in self-recovery capacity, residual deformation of the fabricated concrete structure under the earthquake action is reduced, obvious plastic deformation of components of a main body structure is avoided, and the overall structure is very reasonable and stable.
本发明公开一种组合耗能式且具有自恢复特性的梁柱节点装置，包括混凝土柱和混凝土梁以及用于连接混凝土柱和混凝土梁的变摩擦耗能装置和剪切钢板耗能装置；所述的变摩擦耗能装置包括U形的内摩擦连接钢板、双U形的中摩擦连接钢板以及板状的外摩擦连接钢板；所述的内摩擦连接钢板固定于混凝土柱下端，而中摩擦连接钢板的上下端均设置成U形结构，下端U形结构固定于混凝土梁上，而内摩擦连接钢板则相应固定在中摩擦连接钢板上端的U形结构中。本装置形式简单，安装方便，抗震性能好，稳定可靠，自恢复能力非常强，降低装配式混凝土结构在地震作用下的残余变形，避免主体结构的构件出现明显的塑性变形，整体结构非常合理稳定。
