| 摘 要： | 纤维增强复合材料（FRP）具有高强轻质和耐腐蚀的优点，适合于腐蚀环境和大跨轻质结构．针对大跨度空间网格结构中的杆件，对拉挤玻璃纤维增强复合材料（GFRP）圆管的轴心受力性能进行了试验研究．首先通过短管受压试验得到了GFRP管的基本力学性能参数；然后进行了4组不同长细比共12根GFRP长管的轴心受压试验，研究了其稳定性能．最后根据文献和试验结果，提出了基于Perry公式的GFRP管轴心受压屈曲破坏承载力的计算公式．能较好地预测GFRP长管的轴压屈曲破坏．

| Abstract: | Fiber reinforced polymer (FRP) is suitable for structures in corrosive environment and long-span light-weight structures due to its high-strength, light-weight, and anti-corrosive qualities. The behavior of pul-truded glass fiber reinforced polymer (GFRP) pipes, which are the members of long-span lattice structures, un-der axial compression was investigated by tests. Short GFRP pipes were first tested to determine the basic me-chanical properties. Then the stability of long GFRP pipes was studied by axially compressive tests in four groups with different slenderness ratios, 12 specimens totally. Based on results of the tests and literature, the formula of the buckling load of composite pipes under axially compressive load was presented based on Perry for-mula. It can well predict the buckling failure load of long GFRP pipe under axial compression. |
