Construction sequence — where it appears
Named by 2 essays across 2 fields — each of them below, with the objects they name alongside it.
Also named here as propping — the same set of essays touches all of them, so they are one junction rather than several.
The structure that was never complete
Every analysis in this collection is of a finished structure loaded once. Real ones are built in pieces, and each piece carries whatever was present at the moment it became structural — so the stress in a member depends on when it arrived, which appears nowhere on any drawing.
Built to the wrong shape on purpose
A cambered beam is fabricated curved upward so that load bends it down to something like straight. Nothing in the analysis changes, no stress anywhere is altered, and almost every mistake made with it is a bookkeeping mistake about which loads count.
