玻璃钢管混凝土柱力学性能的试验研究

Experimental research on the mechanical properties of concrete filled FRP tubular column

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 。

The feasibility of concrete filled wrapped FRP tubular column was discussedThe mechanical property of concrete filled FRP tubular short column under axial compression was testedThe experimental result indicates that the confinement offered by FRP tubular can improve the strength and toughness of column and the axial loadbearing capacity of FRP tubular under bidirection load is improved greatlyIt has many good qualities,such as lightweight,high strength,noncorrosive,etcIt can be used in the corrosive environment and building structure that selfweight is limited strictlyThe application way of the concrete filled FRP tubular column is expanded
