Lifting type concrete-steel combined self-resetting column foot joint and assembling method thereof
The invention discloses a lifting type concrete-steel combined self-resetting column foot joint and an assembling method thereof. A formed steel reinforced concrete column and an upper steel column are mechanically connected through a steel plate with superelasticity, a limiting key and angle steel by using bolts to form a stress whole. The column inflection point is improved by lifting the column foot, so that the damage of the column foot under an earthquake is effectively reduced; on the basis, a high-strength prestress screw rod is arranged in a full-length mode, so that the integrity and rigidity of the stress whole are enhanced, the energy consumption behavior of the stress whole has precedence, the stress whole can effectively work cooperatively with the steel plate with superelasticity, and the column foot has more excellent self-resetting performance. The invention further provides an assembling method of the lifting type concrete-steel combined self-resetting column foot joint. The method has the beneficial effects that when an earthquake action is borne, good self-resetting and energy consumption characteristics are achieved; and the bolt connection mode is convenient for construction and replacement and disassembly of elements after the earthquake.
本发明公开了一种抬高式混凝土‑钢组合自复位柱脚节点及其组装方法，所构成的型钢混凝土柱与上部型钢柱使用螺栓通过具有超弹性的钢板、限位键、角钢将该两部分进行机械连接从而形成一个受力整体。通过抬高柱脚使柱反弯点提高，以有效的减小柱脚在地震下的损伤，在此基础上通长布置的高强预应力螺杆，不仅强化了这一受力整体的整体性和刚度，还使其耗能行为有了先后性，可有效地与具有超弹性的钢板协同工作，使得柱脚具备更优异的自复位性能。本发明还提供了一种抬高式混凝土‑钢组合自复位柱脚节点的组装方法。本发明的有益效果在于：受到地震作用时，具有良好自复位和耗能特性；螺栓连接的形式便于施工以及震后的元件更换与拆除。
