摘要
钢管活性粉末混凝土是一种新型钢管超高强混凝土组合结构,具有高强度、高延性等优良力学性能。综述了钢管RPC的特性;总结了钢管RPC短柱的力学性能及承载力计算式;介绍了钢管RPC长柱及偏压柱的试验研究成果,以及钢管RPC截面黏结性能和有限元模拟等方面的研究成果。在分析基础上,提出了钢管RPC柱有待深入研究和亟待解决的问题。
Reactive powder concrete filled steel tube （ here in after referred to as RPC - filled steel tubular column） is a new kind of steel tube high strength concrete composite structure, which have excellent mechanical properties such as high strength and high ductili- ty.It summarized the characteristics of steel tube RPC.The mechanical properties of RPC filled steel tubular short column were summa- rized and the beating capacity calculation formula. Introduces the RPC filled steel tube long column and bias column test results, and the cohesive force of steel tube RPC cross section and the research results of the finite element simulation, etc. Based on the analysis, pro- posed the RPC filled steel tube column remains to be further research and the problems to be solved.
