Self-resetting concrete steel column
The invention discloses a self-resetting concrete steel column. The self-resetting concrete steel column comprises a concrete foundation, a circular steel pipe arranged on the concrete foundation andconcrete poured in the circular steel pipe, wherein the two ends of the circular steel pipe are fixedly connected with end plates; and prestressed rib bundles penetrating through the concrete are arranged in the circular steel pipe, through holes are formed in the concrete, the prestressed rib bundles are arranged in the through holes, the plurality of prestressed rib bundles are circumferentiallyarranged in the circular steel pipe in a distributed mode, and the two ends of the prestressed rib bundles are fixedly connected with the end plates. According to the self-resetting concrete steel column, the prestressed rib bundles are arranged in the concrete steel column, the initial tensile stress of the prestressed rib bundles can enable whole building components to automatically restore toinitial positions after the earthquake action, so that the influence or disturbance on the upper structure of a building due to overlarge vertical or horizontal displacement of the components is avoided, the overall collapse of the building structure due to overlarge displacement is prevented, and the workload of building structure repairing can be greatly reduced.
本发明公开了一种自复位混凝土钢柱，包括混凝土基础以及设置于所述混凝土基础上的圆钢管，圆钢管两端固定连接有端板，圆钢管以及浇筑在所述圆钢管内的混凝土，圆钢管内设有贯穿所述混凝土的预应力筋束，所述混凝土内设有通孔，所述预应力筋束设置在所述通孔内，所述预应力筋束设有多个且多个所述预应力筋束周布设置在所述圆钢管内，所述预应力筋束两端与所述端板固定连接，本申请在混凝土钢柱中设置预应力筋束，预应力筋束的初始拉应力可以使得建筑构件整体在地震作用之后自行恢复初始位置，避免构件发生过大的竖向或水平位移从而对建筑上部结构产生影响或扰动，防止因为位移过大而发生建筑结构整体坍塌，可以大大降低建筑结构修复的工作量。
