摘要：

Thin-walled cylindrical shells are widely used as industrial structural members. Owing to low transverse strength, these structures are highly susceptible to the buckling phenomenon when they are exposed to external pressure. Many strengthening methods have been utilized in order to increase the buckling capacity of such structures among which is employing stiffeners in different forms connected to the surface of these structures. This study is aimed at a new approach for strengthening in which vertical corrugations were introduced on 11 cylindrical shell specimens under uniform external pressure. The results showed a considerable increase in the buckling capacity of such structures. (C) 2015 Elsevier Ltd. All rights reserved.
