近年来，越来越多的高震级地震对大型薄壁钢圆筒结构的安全性和完整性构成了威胁。为了发展可持续的经济和基础设施，必须加强现有的坦克。在这项研究中，我们调查的增强效果的圆周CFRP层的增加承载能力的TSC在压缩载荷下，通过有限元分析（FEA）和实验。结果表明，碳纤维布，特别是高强度碳纤维布，可以提高TSC的承载能力。此外，数值计算结果与实验结果吻合良好。
Recently, the security and integrity of large thin-walled steel cylinders (TSCs) have been threatened by an increasing number of high-magnitude earthquakes. To develop a sustainable economy and infrastructure, existing tanks must be strengthened. In this study, we investigate the strengthening effects of circumferential CFRP layers on the increasing load-carrying capacities of TSCs under compressive load through finite element analysis (FEA) and experiments. The results show that circumferential CFRP layers, particularly high-strength CFRP sheets, can increase the load-carrying capacity of TSCs. In addition, numerical results are found to correspond well with experimental results.
