Self-resetting composite structure beam-column joint and construction method thereof
The invention discloses a self-resetting composite structure beam-column joint and a construction method thereof.The self-resetting composite structure beam-column joint comprises an I-shaped steel beam, T-shaped connecting pieces, friction components, a square steel tube concrete column and SMA screws, the I-shaped steel beam is horizontally arranged on the side edge of the square steel tube concrete column, and the T-shaped connecting pieces are symmetrically arranged on the outer side of the beam end of the I-shaped steel beam up and down; one end of the T-shaped connecting piece is fixed with a flange plate of the I-shaped steel beam through a third connecting bolt, and the other end of the T-shaped connecting piece is connected with the square steel tube concrete column through an SMA screw rod; the friction components are symmetrically arranged on the two sides of a web of the I-shaped steel beam, one end of each friction component is fixed to the side wall of the square steel tube concrete column through a first connecting bolt, and the other end of each friction component is connected with the web of the I-shaped steel beam through a second connecting bolt. According to the invention, the self-resetting capability is provided for the joint through the superelasticity of the SMA screw rod; friction components are used for providing good energy dissipation capacity, site welding is not needed in the joint assembly construction process, and the requirements for industrialization and assembly of a composite structure building are met.
本发明公开了一种自复位组合结构梁柱节点及其施工方法，包括工字型钢梁、T型连接件、摩擦构件、方钢管混凝土柱及SMA螺杆，工字型钢梁水平设置在方钢管混凝土柱的侧边，T型连接件上下对称设置在工字型钢梁的梁端外侧；T型连接件的一端通过第三连接螺栓与工字型钢梁的翼缘板固定，另一端通过SMA螺杆与方钢管混凝土柱连接；摩擦构件对称设置在工字型钢梁的腹板两侧，摩擦构件的一端通过第一连接螺栓与方钢管混凝土柱的侧壁固定，另一端通过第二连接螺栓与工字型钢梁的腹板连接；本发明通过SMA螺杆的超弹性为节点提供自复位能力；利用摩擦构件提供良好的耗能能力，节点装配施工过程无需现场焊接，满足组合结构建筑工业化和装配化的要求。
