摘要: PVC-FRP管混凝土柱是一种新型的组合结构,它是在PVC-FRP管内浇筑混凝土形成的。为验证PVC-FRP管混凝土结构的优越性,将PVC-FRP管混凝土柱的力学性能与已有约束混凝土柱进行比较,包括承载力、应力-应变关系和延性。结果表明,PVC-FRP管混凝土具有承载力高、延性好,施工方便、自重小、耐久性好等优点。PVC-FRP管混凝土柱为结构体系的创新提供新的形式,具有广阔的应用前景和发展空间。Abstract: PVC-FRP confined concrete column is a new structural system, which is formed by constructing concrete into PVC-FRP tube. To verify the advantage of PVC-FRP confined concrete column, the mechanical behavior of PVC-FRP confined concrete column are compared with that of confined concrete column, including bearing capacity, stress-strain relationship and ductility. Results show that PVC -FRP confined concrete column features high bearing capacity, good ductility, convenient construction, light weight and good durability. PVC-FRP confined concrete column provide a new form for the inven tion of structural system, which has a brigh t future and development space.
