High-energy-consumption high-bearing-capacity self-resetting beam-column joint
The invention provides a high-energy-consumption high-bearing-capacity self-resetting beam-column joint which comprises a column structure, a beam connecting block is arranged on the side face of a concrete column in a protruding mode, the beam connecting block is connected with a column end steel member, the column end steel member is connected with a beam end steel member, and the beam end steel member is connected with a concrete beam. The column end steel member and the beam end steel member have the same structure, and the middle parts are hinged; energy dissipation structures and elastic reset structures are mounted above and below the hinged joint of the column end steel member and the beam end steel member; the energy dissipation structure comprises an energy dissipation steel bar, a plurality of cone frustum parts facing the same direction are formed on the energy dissipation steel bar in the length direction, and the thick ends of the cone frustum parts extend to form limiting convex rings. The beam-column joint is high in energy dissipation capacity, good in self-resetting performance and easy to repair, so that the structure has excellent anti-seismic performance and self-resetting capacity under a high-strength earthquake.
本发明提供了一种高耗能高承载力自复位梁柱节点，包括柱结构，混凝土柱侧面凸起有梁连接块，梁连接块连接有柱端钢构件，柱端钢构件连接有梁端钢构件，梁端钢构件连接有混凝土梁；所述柱端钢构件和梁端钢构件结构相同，且中部铰接连接；柱端钢构件和梁端钢构件的铰接连接处的上方和下方均安装有耗能结构和弹性复位结构；所述耗能结构包括耗能钢棒，耗能钢棒上沿长度方向形成有若干朝向相同的圆锥台部，圆锥台部的粗端延伸形成限位凸环。本发明耗能能力强、自复位性能好、易修复的梁柱节点，使得结构在高强度地震下具有优异的抗震性能和自复位能力。
