10.5. Shell and flange sizing

In the case of a steel tubular tower, the main output of the design exercise is the sizing of the shell segments and of the welded and bolted connections. In the following two sections, an overview of the limit state verifications and of the structural criteria to be satisfied for these components is provided. The physical principles are easily extended to other tower configurations, with the addition of specific verifications. For lattice towers, the size of the individual members and the qualification of the joints are the principal design outcome. They can be sized by performing member and joint checks as specified by appropriate standards (eg, Refs [19,31]). In the case of concrete towers, the size and arrangement ...
