摘　　要：采用新型纤维材料替代传统的普通钢筋来解决钢筋混凝土的锈蚀问题已得到广泛的认可,如果此类新型材料在实际工程中能得到更多的应用,其力学性能还需进一步的研究。提出了两种有关GFRP(玻璃纤维筋)箍筋间距对轴心受压柱承载力影响的理论计算公式,通过ABAQUS有限元分析软件模拟值对比证明,该理论计算公式对GFRP筋混凝土柱在轴心荷载作用下的极限承载力计算有很大的参考价值。The use of new fiber materials to replace the traditional ordinary steel to solve the problem of corrosion of reinforced concrete had been widely recognized. If his new materials can be applied more in the actual project,the rele-vant force characteristics need to be studied. ＂Pwo kinds of theoretical formulas for the influence of GFRP （glass fiberreinforced concrete） stirrup spacing on the bearing capacity of axial compression columns were presented. By means ofthe formulas comparing with the results of ABAQUS finite element analysis software,the formula has great reference value about the ultimate bearing capacity of GFRP reinforced concrete columns under uniaxial loading.
