Friction energy dissipation type connecting joint for high-strength concrete filled steel tubular column and precast beam
The invention relates to a high-strength concrete filled steel tubular column and precast beam friction energy dissipation type connecting joint, in particular to the technical field of structural disaster prevention and reduction. The cold-bending high-strength thin-wall concrete-filled steel tube column assembly comprises a cold-bending high-strength thin-wall concrete-filled steel tube column, a steel-concrete composite beam, a first connecting piece arranged on one side of the cold-bending high-strength thin-wall concrete-filled steel tube column, a second connecting piece arranged at the beam head end of the steel-concrete composite beam, and a self-resetting friction energy dissipation damper. Under the action of a large earthquake, deformation of the SMA bolts and friction energy dissipation of the grooved steel plates are guided to work together, and the self-resetting friction energy dissipation function is achieved. The friction type energy dissipation node is simple in structure, clear in stress, efficient and convenient in assembly type construction, excellent in anti-seismic performance and self-resetting characteristic, and capable of being applied to important projects such as large public buildings with high anti-seismic and disaster prevention requirements.
本发明涉及一种高强钢管混凝土柱与预制梁摩擦耗能式连接节点，特别涉及结构防灾减灾技术领域。本发明包括冷弯高强薄壁钢管混凝土柱、钢混凝土组合梁、设置在所述冷弯高强薄壁钢管混凝土柱一侧的第一连接件、设置在所述钢混凝土组合梁梁头端的第二连接件、自复位摩擦耗能阻尼器，小震及中震作用下由夹板及盖板摩擦耗能，大震作用下引SMA螺栓变形及刻槽钢板摩擦耗能共同工作，具备自复位摩擦耗能功能。本专利提出的摩擦式耗能节点，构造简单、受力明确、装配式建造高效便捷，具备优良的抗震性能及自复位特性，可应用于大型公共建筑等对抗震防灾需求较高的重要工程中。
