钢管混凝土,顾名思义就是把混凝土灌到钢管内。用这样的方法制成的构件,是近年来国内外新发展的一种复合结构。众所周知,当薄型钢管单独承压时,往往由于管壁失稳而失效,除整体失稳外,这不是强度不够,可是当素混凝土园柱体单 Concrete-filled steel tube, as its name suggests, is poured concrete into steel pipes. The components made in this way are newly developed composite structures at home and abroad in recent years. As we all know, when the thin steel pipe is under pressure alone, it often fails due to the instability of the pipe wall. In addition to the overall instability, this is not a lack of strength, but when the plain concrete cylinder column single
