新型FRP-混凝土组合柱力学性能研究综述

Overview on Mechanical Properties of Novel FRP-Concrete Composite Columns

纤维增强复合材料(FRP)在建筑结构中的应用有效规避了钢材的锈蚀问题。充分利用FRP和传统建材的材料性能优势,形成了多种新型FRP-混凝土组合结构构件形式,实现了建筑结构安全性和耐久性的更高追求。文章通过3种典型组合柱"FRP-混凝土-钢管双管柱、FRP约束钢管混凝土柱、钢管-混凝土-FRP-混凝土柱"在力学性能试验和理论计算方面的研究成果总结介绍,为建筑结构中的材料优化组合提供新思路,展现FRP-混凝土组合柱与海水海砂混凝土结合的发展前景。

The application of fiber-reinforced polymer/plastic(FRP)in building structures effectively alleviates the problem of steel corrosion.Utilizing the advantages of FRP and traditional building materials,multiple types of novel FRP-concrete composite members have been put forward to realize higher safety and durability of building structures.By selecting three typical composite columns:FRPconcrete-steel double-skin tubular columns,FRP-confined concrete-filled steel tubular columns,steel-concrete-FRP-concrete columns,their mechanical properties were introduced and summarized from experimental studies and theoretical calculations,and the future development of FRP-concrete composite columns with seawater and sea-sand concrete was illustrated.
