本文探讨了玻璃钢 (FRP)缠绕管增强混凝土柱的可行性 ,并对单轴压力下玻璃钢管混凝土短柱的力学性能进行了试验研究。试验结果表明 :玻璃钢管提供的紧箍力 ,不仅使混凝土柱的强度和韧性得到较大提高 ,而且玻璃钢管也在双向荷载作用下 ,轴向承载力大大提高。玻璃钢的轻质高强、耐腐蚀等特性 ,使得玻璃钢管混凝土柱可以应用在腐蚀性介质环境及对结构自重要求比较苛刻的建筑结构中 ,从而为玻璃钢在建筑工程中的应用开辟了新的方向
In this paper, the feasibility of reinforced concrete columns with glass fiber reinforced plastic (FRP) wound tubes is discussed. The mechanical properties of concrete filled CFST columns under uniaxial compression are studied. The test results show that the tight hoop force provided by the FRP pipe not only greatly enhances the strength and toughness of the concrete column, but also significantly increases the axial load capacity of the FRP pipe under the bidirectional load. FRP lightweight high strength, corrosion resistance and other characteristics, making the FRP concrete column can be used in corrosive media environment and the structural requirements of the more demanding building structure, which FRP in the construction of the application has opened up a new direction
