FOLDED PLATES
The design of folded plate roof structures follows the design of barrel shells, but is much simpler because the elements are all essentially beams.
1. Support the folded plate at its longitudinal edges by frequent columns as was suggested for barrel shells.
2. Analyse and design the slab element as a continuous beam on fixed supports, including the first spans, normally a simple support. If it is haunched, then as a continuous haunched beam.
