High-strength and high-ductility concrete filled steel tubular column
The invention provides a high-strength and high-ductility steel pipe concrete column which comprises a rectangular outer steel pipe and arc-shaped inner steel plates connected to each steel pipe face of the inner side of the rectangular outer steel pipe, the arc-shaped inner steel plates and the steel pipe faces of the inner side of the rectangular outer steel pipe form four closed and non-intersecting cavities, and the portion outside the inner cavities of the rectangular outer steel pipe is a core area. The core area is filled with concrete; the arc-shaped inner steel plate provides constraint on the concrete column core similar to a circular steel pipe, so that concrete in all areas in the outer steel pipe can be well restrained, meanwhile, the arc-shaped inner steel plate provides a supporting effect for the outer steel pipe, local buckling deformation of the rectangular outer steel pipe is effectively delayed, and the service life of the outer steel pipe is prolonged. Therefore, the concrete filled steel tubular column member has high strength and good ductility.
本申请提供一种高强度高延性的钢管混凝土柱，包括矩形外钢管和连接在矩形外钢管内侧每个钢管面的弧形内钢板，弧形内钢板与矩形外钢管内侧的钢管面形成四个封闭且互不相交的腔体，矩形外钢管内腔体以外为核心区域，核心区域内填充混凝土；弧形内钢板提供了类似圆钢管对混凝土柱芯的约束，使外钢管内部所有区域的混凝土都能受到良好的约束作用，同时弧形内钢板为外钢管提供支撑作用，有效延缓矩形外钢管的局部屈曲变形，使得钢管混凝土柱构件具有高强度和良好的延性。
