Özet

© 2023, Korean Society of Steel Construction.Thin-walled cylindrical tanks are used in many civil engineering applications. In the past ten years, various methods have been used to confinement the cylindrical tanks; one of these methods is using CFRP. In this study, the tanks were confinement by using CFRP (The CFRP confinements were decided for 50 mm in width) in two different ways (Spiral (S) and horizontal (H)) at different distances (100,200 and 300 mm), and the effect of CFRP on the buckling capacity was examined. The models present how the spiral and horizontal CFRP confinement can improve buckling capacity. Results show that the gradual decreases in the initial, overall, and collapse buckling loads resulted from increasing CFRP strip distance of 100 mm to 300 mm in the two groups. Also, the results observed are generally by some of the international standards and the theories related to buckling.
