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。
PVC-FRP pipe Concrete column is a new type of composite structure, which is formed by pouring concrete in PVC-FRP pipe. In order to verify the superiority of PVC-FRP pipe concrete structure, the mechanical properties of PVC-FRP pipe concrete columns are compared with the existing confined concrete columns, including bearing capacity, stress-strain relationship and ductility. The results show that PVC-FRP pipe concrete has the advantages of high bearing capacity, good ductility, convenient construction, small dead weight and good durability. The PVC-FRP pipe concrete column provides a new form for the structural system innovation, has broad application prospects and development space.
