Extensive studies on ring-stiffened, cylindrical shells subject to uniform axial compression were conducted in the 1960s and 1970s. The stiffeners’ beneficial effect on the axial buckling behavior was well recognized. However, standards for typical civil engineering structures do not provide detailed rules that allow to take into account the increased buckling capacity. With the trend towards more sustainable structures, the use of very thin-walled structures, which are prone to axial buckling, became more common and improved rules for the axial buckling check became necessary to allow for economic designs. In this paper, one approach to predict the buckling resistance of ring-stiffened shells under axial compression is presented. The proposed procedure allows the determination of failure loads of closely and widely stiffened shells. The provided rules are directly applicable to any typical civil engineering structure that buckles elastically.
