Summary
Designing a structure by the method of Lower Bound rarely considers the supports: that often, sizing the 'main beam' is key. One difficulty is how to interpret the nature of supports themselves in a Lower Bound analysis context. Some clarity is given for a nominal multi-span beam where one of its supports is realised differently in three ways.
