摘要:

利用3组共9根玻璃纤维增强复合材料（GFRP）管件轴心受压稳定性试验，观察其破坏过程及破坏特征，分析研究管件变形、极限承载力及破坏形式，同时建立了管件的ANSYS有限元模型.结合试验及有限元分析结果，推导出GFRP圆管构件实用的极限承载力计算公式，其计算结果与试验结果吻合较好.

Abstract:

Stability test of the axial compression of the circular tube members of 3 groups of 9 glass fiber reinforced plastic (GFRP） was completed. The failure process and failure characteristics were observed, and the deformation, ultimate bearing capacity and failure mode of the components were analyzed. The finite element model of ANSYS was set up to analyze the ultimate bearing capacity of different sizes of GFRP circular tube members. A practical calculation formula of ultimate bearing capacity of GFRP circular tube members was derived, which is in good agreement with the experiment and the finite element analysis results.

Key words: glass fiber reinforced plastic(GFRP) axial compression test ultimate bearing capacity finite element analysis
