摘要
介绍分析了在钢管混凝土短柱中配置纵向钢筋的试验及结果,研究表明,与普通的钢管混凝土柱相比,配筋钢管混凝土柱的承载力和变形性能都有较大的提高,因此可以采用在钢管内配置纵向钢筋的方法来减小钢管的壁厚,使得受火钢管退出工作后,仍能成为钢筋混凝土柱而具有一定的承载能力。
The paper introduces and analyzes experimental results of bar-reinforced concrete filled steel tubular stub columns under axial loads.This study shows that the capabilities and deformation properties of bar-reinforced concrete filled steel tubular columns are greatly improved than that of concrete filled steel tubular columns.So the using of bar-reinforced concrete filled steel tubular column can reduce steel pipe wall thickness.After the steel pipes are out of work by the fire,bar-reinforced concrete filled steel tubular columns can still be reinforced concrete columns and have a certain bearing capacity.
