Covers the building of a simple model of a 3-span slab bridge with twin deep ribs, using shell and beam elements and constraint equations to tie the surfaces and beams together to ensure composite action. Tendon profiles are defined and assigned to the model, requiring specification of tendon properties, prestress force and jacking details, and selection of the lines of the model to which they apply. The deformed shape from self-weight and prestress loading is viewed for each in isolation, prior to looking at the effects of both in a load combination.
