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。
Under the action of axial compression or bending, a series of experimental studies on the performance of stainless steel concrete short columns and slender columns were carried out and compared with those of short columns. The results show that the composite column has good performance and can be widely used as a structural member. The results of the tests are compared with the existing design specifications of traditional carbon steel concrete columns, such as Australian Standard AS5100 (2004), American Standard AISC (2005), Chinese Code DBJ / T13-51-2010 and European Code Eurocode4 (2004). The results show that these specifications are conservative in predicting the bearing capacity of short columns and slender columns.
