Self-resetting concrete-filled steel tubular column-steel beam joint
The invention provides a self-resetting concrete-filled steel tubular column-steel beam joint. The self-resetting concrete-filled steel tubular column-steel beam joint comprises a concrete-filled steel tubular column, a ribbed I-shaped beam, prestressed reinforcements, arc-shaped angle steel, bolts, an anchor bearing plate and stiffening ribs. A reserved hole channel is formed in the concrete-filled steel tubular column. Prestressed reinforcements penetrate through the reserved hole channel and stiffening rib hole channels, one ends of the prestressed reinforcements are fixedly connected with the concrete-filled steel tubular column, and prestress is tensioned. The arc-shaped angle steel is arranged on the upper side and the lower side of the ribbed I-shaped beam respectively and connected with the concrete-filled steel tubular column and the ribbed I-shaped beam through bolts. According to the joint, the prestressed reinforcements can enable the structure to be reset to the initial state after the earthquake action, the stiffening ribs can improve the torsion resistance of the structure, the arc-shaped angle steel has the good energy dissipation capacity, the overall stress performance of the structure is good, the residual deformation of the structure after the earthquake is small, and the excellent earthquake-resistant performance is achieved.
本发明提供了一种自复位钢管混凝土柱‑钢梁节点，包括：钢管混凝土柱、带肋工字梁、预应力筋、弧形角钢、螺栓、锚垫板、加劲肋。所述钢管混凝土柱内设置预留孔道；预留孔道和加劲肋孔道内穿过预应力筋，预应力筋的一端与钢管混凝土柱固定连接，并张拉预应力；弧形角钢分别设置在带肋工字梁的上下两侧，并通过螺栓连接钢管混凝土柱和带肋工字梁。在本发明中，预应力筋可使结构在地震作用后恢复到初始状态，加劲肋可提高结构的抗扭性能，弧形角钢具有较好的耗能能力，该结构整体受力性好，结构的震后残余变形较小，具有优良的抗震性能。
