摘　　要：纤维增强材料(FRP)管-混凝土-钢管构件是一种新型组合构件,由外部FRP管、内层钢管以及两者之间填充的混凝土三部分组成,三种材料的协同互补和共同工作使该组合构件具有许多优于现有组合构件的力学性能,该组合构件外管和内管同心放置可用于受压构件,偏心放置可用于受弯构件。主要综述国内外关于该组合构件的最新研究成果,主要包括轴压、偏压和受弯作用下的破坏模式、主要影响因素,以及构件承载力实用计算式等。Hybrid FRP-concrete-steel double-skin tubular member is a new form of hybrid structural member composed of an inner steel tube,an outer FRP tube and a concrete infill between them. In this type of new hybrid member,the three constituent materials are optimally combined to achieve several advantages not available with existing columns. The two tubes may be concentrically placed to produce a section more suitable for compression members,or eccentrically placed to produce a section more suitable for flexural members. This paper summarizes the following areas that have received many researches： the failure mode and the influence factors under different loading,the formulas to calculate ultimate capacity under different loading.
