Novel self-resetting steel structure beam column joint
The invention discloses a novel self-resetting steel structure beam-column joint, which belongs to the technical field of buildings, and comprises a steel column, the right side surface of the steel column is in lap joint with the left side surface of a steel beam, the upper surface and the lower surface of the inner wall of the steel beam are respectively in lap joint with two lower base plates, and the upper surface and the lower surface of the steel beam are respectively in lap joint with two flat steel plates. By arranging the angle steel, the reset ribs and the first sliding holes, the flat steel plate and the angle steel need to overcome mutual contact static friction force, when the static friction force is changed into dynamic friction, the flat steel plate and the angle steel are synchronously subjected to pulling force of the reset ribs, the reset ribs are in a certain-degree deformation state in the process of being subjected to large pulling force, damping is formed for energy dissipation, and energy dissipation is achieved. And when the vibration is finished, the length of the reset rib begins to reset, so that the overall stability under the large vibration amplitude can be realized, automatic energy consumption and active reset can be realized, and metal fatigue and damage of parts are avoided while the good anti-seismic performance of the structure is guaranteed.
本发明公开了一种新型自复位钢结构梁柱节点，属于建筑技术领域，其包括钢柱，所述钢柱的右侧面与钢梁的左侧面搭接，所述钢梁内壁的上下两表面分别搭接有两个下垫板，所述钢梁的上下两表面分别搭接有两个平钢板。通过设置角钢、复位筋和第一滑孔，其平钢板与角钢之间需要克服相互接触的静摩擦力，当静摩擦力变为动摩擦时，其同步受到若干个复位筋的拉力，使其若干个复位筋受到较大拉力的过程中出现一定程度的形变状态，形成阻尼进行耗能，当震动结束时，复位筋长度开始复位，这种方式能够实现在较大震动幅度的下的整体稳定，使其能够实现自主耗能，以及主动复位，保障结构良好抗震性能的同时不会有部件出现金属疲劳及损伤。
