摘要
对CFRP外部约束钢管混凝土构件的研究进展和应用情况进行了系统、深入的阐述,分析了承载力等结构性能的理论研究、数值模拟和试验研究成果,探讨了CFRP外部约束钢管混凝土构件在实践中的应用。结果表明:CFRP外部约束钢管混凝土构件改善了CFRP约束混凝土结构和钢管混凝土结构的性能,其增强效果受CFRP厚度、长径比、缠绕方向等多种因素影响。
The research progress and application of concrete filled steel tubular structure with the external strengthening of CFRP are expounded systematically and in-depth. The theoretical study, numerical simulation, experimental research results of structure behavior, such as bearing capacity, are analyzed. Then the practical application of concrete filled steel tubular structure with the external CFRP constraint is discussed. The results indicate that the concrete filled steel tubular structure constrained by CFRP composite materials improves the structure behavior of both concrete filled steel tube and concrete confined with CFRP, and the reinforcing performance is effected by the thickness of CFRP, slenderness ratio and fiber orientations.
