On the layout of a least weight single span structure with uniform load

Some comments and improvements

Abstract

Beghini et al. (Struct Multidisc Optim 50:49–64, 2014) have published a very interesting paper arriving to practically the same nearly optimal solutions for the so named “bridge problem” that the writers published a year before, but using an alternative and remarkable approach to the problem. In spite of this general agreement, the writers think that some details of the paper can be improved and there are results that can be given a clear and meaningful interpretation, thanks to an old and practically unknown theorem on optimal slenderness.
