摘　　要：钢管混凝土结构较弱的耐腐蚀性导致结构的承载能力降低,进而引发了重大的安全担忧。近年来,CFRP作为一种轻质高强的复合材料,因其能够有效提升结构的承载能力及耐腐蚀性而备受关注。本文通过对1根钢管混凝土拱和3根CFRP约束的钢管混凝土拱进行平面内五点加载试验,探究不同因素对结构构件承载能力的影响。通过有限元软件进行数值模拟以验证试验结果,确保模型的准确性和可靠性,为后续数值模拟和工程实践提供理论基础。The weak corrosion resistance of concrete-filled steel tube structures leads to a reduction in the bearing capacity of the structures,which in turn raises significant safety concerns.In recent years,CFRP,as a kind of lightweight and high-strength composite material,has attracted much attention because of its ability to effectively improve the bearing capacity of structures.In this paper,a five-point loading test was carried out on one concrete-filled steel tube arch and three concrete-filled steel tube arches confined by CFRP to explore the influence of different factors on the bearing capacity of structural members.Numerical simulation was carried out by finite element software to verify the test results,ensure the accuracy and reliability of the model,and provide a theoreticalbasis for subsequent numerical simulation and engineering practice.
