Rectangular concrete-filled steel tubular column and preparation method
The invention relates to a rectangular concrete-filled steel tubular column. The rectangular concrete-filled steel tubular column comprises a first long-side steel plate, a second long-side steel plate, a first short-side steel plate and a second short-side steel plate, wherein the first long-side steel plate is parallel to the second long-side steel plate; the first short-side steel plate is parallel to the second short-side steel plate; the width-thickness ratios of the first long-side steel plate, the second long-side steel plate, the first short-side steel plate and the second short-side steel plate are equal respectively; the first long-side steel plate, the first short-side steel plate, the second long-side steel plate and the second short-side steel plate are sequentially connectedend to form a closed-loop rectangular steel tube; and the rectangular steel tube is filled with concrete. When the rectangular concrete-filled steel tubular column is pressed, the first long-side steel plate, the second long-side steel plate, the first short-side steel plate and the second short-side steel plate can be bent simultaneously, so that the utilization rate of materials is increased, the bearing capacity and the ductility are enhanced, and the seismic performance of a component is improved. The invention further relates to a preparation method of the rectangular concrete-filled steel tubular column.
本发明涉及一种矩形钢管混凝土柱，包括第一长边钢板、第二长边钢板、第一短边钢板与第二短边钢板，第一长边钢板平行于第二长边钢板，第一短边钢板平行于第二短边钢板，第一长边钢板、第二长边钢板、第一短边钢板与第二短边钢板的宽厚比分别相等，第一长边钢板、第一短边钢板、第二长边钢板与第二短边钢板依次首尾连接形成闭环的矩形钢管，矩形钢管内填充有混凝土。在受压时第一长边钢板、第二长边钢板、第一短边钢板与第二短边钢板能够同时达到屈曲，提高了材料的利用率，增强了承载力和延性，提升了构件抗震性能。本发明还涉及一种矩形钢管混凝土柱的制备方法。
