不锈钢管混凝土短柱及细长柱的性能

在轴压或压弯作用下,对不锈钢管混凝土短柱和细长柱的性能进行一系列试验研究,并与短钢管柱试验对比。结果表明:组合柱的性能很好,可广泛用作结构构件。将试验结果与传统碳素钢管混凝土柱的现有设计规范对比,如澳大利亚规范AS5100(2004),美国规范AISC(2005),中国规范DBJ/T13-51-2010和欧洲规范Eurocode4(2004)。结果表明:这些规范在预测短柱和细长柱的承载力方面都比较保守。

Behaviour of Short and Slender Concrete-Filled Stainless Steel Tubular Columns

In this paper,a series of tests were carried out on short and slender concrete-filled stainless steel tubular columns to explore their performance under axial compression or combined actions of axial force and bending moment.Empty short steel hollow sections were also tested for comparison.The test results showed that the performance of the composite columns was quite good and have the potential to be used extensively as structural members.Comparisons of the test results were also made with several existing...
