Abstract

A cantilever column is loaded by compression and bending, and the horizontal displacement of the column top as well as the outside diameter of the cylindrical shell are limited. The strengthening of the column is performed in the lower part of the column only. Three structural versions of the column are optimized and compared to each other. Firstly, the unstiffened circular shell is optimized, and it is found that the required large thickness is unsuitable for fabrication. Secondly, the stringer-stiffened circular shell is optimized. The halved rolled UC section stringers are used only in the lower part of the column; the distance of the interruption of stiffeners is also optimized. It is found that the required shell thickness is unsuitable for fabrication. Thirdly, a new structural version, the cellular shell is used. Cellular shells are constructed from two circular cylindrical shells, and a grid of stiffeners welded between them. They have similar advantages than the cellular plates, namely they can produce a large stiffness with small structural height. Their smooth surface is suitable for corrosion protection, and they are more aesthetic than the stringer-stiffened shells.
