摘要

摘要: 不锈钢管混凝土柱在海港工程、海洋工程等腐蚀环境下具有较好的应用前景。为进一步提升此类结构的性能,提出了一种组合结构,即内置钢骨的不锈钢管超高性能混凝土柱。同时,以径厚比、长径比和含骨率等为参数设计制作了6个短柱和8个中长柱试件,进行了轴心受压试验和有限元模拟分析,研究了试件的破坏形态、破坏机理,以及相关参数对试件力学性能的影响规律。结果表明:试件的承载力及延性随着径厚比和长径比的减小而增大,随着含骨率和内置钢骨强度的增加而增加;试件延性随着核心混凝土强度增大而降低,承载力与之相反。根据试验和有限元的分析结果,提出了内置钢骨的不锈钢管超高性能混凝土柱的承载力预测模型,为此类结构的工程应用提供了参考。

Abstract: Concrete-filled stainless steel tubular columns show excellent prospects for application in corrosive environments such as harbor engineering and marine engineering. To further develop the performance of such structures, a composite structure, i. e. steel-reinforced ultra-high performance concrete-filled stainless steel tubular column was proposed in this paper. Meanwhile, six short and eight medium-length column specimens were designed and fabricated with the parameters of diameter to thickness ratio, length to diameter ratio, steel profile content ratios, etc. Axial compression experiments and finite element analysis were executed to investigate the failure mode and failure mechanism of the specimens, as well as the influence of relevant parameters on the mechanical performance of the specimens. The results showed that the bearing capacity and ductility of the specimens increased with the decreasing of the diameter to thickness ratios and length to diameter ratios, and increased with the increding of the steel profile content ratios and strength of the pre-embedded steel profile; the ductility of the specimen decreased with the increase in core concrete strength, but the bearing capacity was the opposite. Based on the experimental and finite element results, a prediction model for the bearing capacity of steel-reinforced ultra-high performance concrete-filled stainless steel tubular was proposed, providing a reference for the engineering application of such structures.
