基于FRP的PVC管新型组合结构柱的研究进展

New progress on the study of a new type of hybrid columns based on FRP and PVC

主要分析一种新型的组合结构柱———FRP约束PVC管混凝土柱,通过综合分析该组合柱的基本组合形式、工作性能及其特点,归纳分析了基于FRP的新型组合结构柱的研究进展情况。

Recently,some researching work has been made by domestic and overseas scholars on the hybrid columns based FRP.The main work focuses on FRP-confined concrete-filled steel tubes,FRP-confined masonry columns,hybrid FRP-concrete steel hybrid columns and so on.This paper introduces a new type of hybrid columns based on FRP-confined concrete-filled PVC tubular columns.Through a comprehensive analysis to the basic hybrid types,working performance and its characteristics,the new progress of a new type of hybrid columns based FRP is inducted with an aim to provide a reference for the related researches.
