N2 - In this short communication, a series of novel forms of tubular members made of fiber-reinforced polymer (FRP) grid reinforced ultra-high-performance concrete (UHPC) (referred to as “FRP-UHPC tubular members”) are developed. FRP-UHPC tubular members have excellent mechanical properties, and their excellent performances are demonstrated through three preliminary studies: i) behavior of FRP-UHPC tubular beams under bending; ii) behavior of FRP-UHPC tubular columns under axial compression; and iii) behavior of FRP-UHPC plates with a novel grouting sleeve connection system under bending. The experimental programs and results are briefed in the paper. The proposed FRP-UHPC tubular members are attractive in various structural applications such as pipelines, bridge box girders, permanent formwork of beams/columns, especially in marine environments (e.g., floating structures).
