    摘要:

    为提升拉挤型玻璃纤维复合材料（GFRP）管混凝土组合柱的承载能力，采用碳纤维增强复合材料（CFRP）布，以不同约束方式制作5根试件，并进行轴压试验，得到约束组合柱的破坏模式；通过对CFRP的约束效应及柱的承载性能分析，建立承载力计算模型。研究表明：试件破坏时拉挤型GFRP管及混凝土被压坏，部分试件伴有CFRP条带状撕裂。随着横向约束效应的增加，破坏形态由典型的劈裂破坏向脆性压碎破坏及剪切破坏发展。试件承载力随CFRP间距的减小逐渐增大，CFRP间距<100 mm时试件承载力大幅提高，最大可达1.5倍以上，CFRP间距≥100 mm时，承载力提升并不明显。CFRP间距变化、布置方式对试件变形性能影响显著，可明显改善构件的延性。基于约束混凝土理论，考虑不同CFRP间距及GFRP承载作用效应，建立的试件承载力计算模型计算结果精度较高。

    Abstract:

    In order to improve the carrying capacity of the pultruded glass fiber reinforced plastics (GFRP) tube, five specimens were produced with carbon fiber reinforced plastics (CFRP) cloth with different restraint methods and axial compression tests were conducted. The damage mode of this restrained combined column was obtained. Through the analysis of the CFRP restraint effect and the load-bearing performance of this column, the load-bearing capacity calculation model was established. The results show that the squeezed GFRP and the concrete are crushed when the test piece is damaged, some specimens were accompanied by a band tear of CFRP. Disruption morphology increases with the effect of lateral constraint, development from typical cracking fracture to brittle crushing destruction and shear destruction. The bearing capacity of test parts gradually increases with the decrease of CFRP distance, test piece bearing capacity can be greatly improved at a CFRP distance of <100 mm, Maximum increase of 1.5 times, when the CFRP spacing is ≥100 mm, the improvement of the carrying capacity is not obvious. The change of CFRP spacing and layout mode improved the deformation performance of the test parts significantly, the ductility of the components can be significantly improved. Based on the theory of restrained concrete, the calculation model of specimen bearing capacity established by considering different CFRP spacing and the effect of GFRP bearing action has a high accuracy of calculation results.
