摘要文章进行了1根无肋和5根带肋方钢管混凝土柱的轴压试验,通过改变试件的截面形式对试件的荷载-位移曲线、极限承载力等方面进行研究。结果表明,在含钢率不变的前提下,设置加劲肋的方钢管混凝土的极限承载力低于无肋方钢管混凝土,该试验设置的纵向加劲肋在一定范围内能够改善方钢管混凝土短柱的延性性能。 This paper experimentally tested on one short concrete-filled square steel tubular column and five short concrete-filled square steel tubular columns with ribs and the load-displacement relationship curves,the ultimate bearing capacity have been derived by changing section form.The result shows that,the ultimate bearing capacity of short concrete-filled square steel tubular columns with ribs is less than the one without ribs on the premise of the same amount of steel.The ductility of the stub columns could be improved in certain range by installing longitudinal ribs.
