摘　　要：本文以500kV FRP抢修杆塔真型试验为依托,对几种不同规格及不同长细比的FRP圆管型截面构件进行轴心受压试验。轴心受压构件的稳定承载力是影响FRP构件承载力的关键,通过对玻璃钢受压构件稳定性的试验研究,得到了构件的极限稳定承载力,研究了构件的变形特征、破坏形态及稳定系数;并将试验所得的稳定系数与国内外稳定系数的计算结果对比,得出了适于FRP管材轴心压杆设计的稳定系数公式。This article is on the basis of the 500kV FRP repair tower model test study. Axial compression test was conducted to several different specifications and different slenderness ratio of FRP tube section members. Axial compression member stability bearing capacity is the key factor influencing the bearing capacity of the members. Based on the study of the stability of the glass steel compression members, get the stable bearing capacity of mem- bers. And study their deformation characteristics, failure pattern and stability coefficient. Comparison of the test val- ue of stability coefficient and calculated value from different standards, the writer fitted an axial compression design stability coefficient expression.
