摘要 FRP约束混凝土柱和钢管混凝土柱是两种不同的约束混凝土应用形式。研究表明,对混凝土进行约束,可以明显提高其承载力和延性。钢管混凝土柱破坏前有较大的变形,属延性破坏;FRP约束混凝土柱的破坏具有突然性,但其强度提高的幅度较大。本文对这两种约束混凝土柱的受力性能进行了简要的比较,并总结了FRP约束混凝土柱和钢管混凝土柱研究现状,同时对今后的发展应用进行展望。 Confined concrete is widely applied in practice which includes FRP-strengthened concrete and concrete filled in steel tubular(CFST).It is demonstrated that the load carrying capacity and durability can be improved greatly for concrete after confinement.Notable deflection can be observed before destruction for CFST columns.FRP-strengthened concrete has more significant improvement of load-carrying capacity although its destruction is brittle.A summary and a brief conparison between FRP-strengthened concrete ...
