Simple post-tensioned bridge - Part 1 (deck modelling)

Shows import and building of a model of a 3-span slab bridge with twin deep ribs, using beam and shell elements. Constraint equations are used to tie the surfaces and beams together to ensure composite action. Concrete material, supports and gravity are assigned prior to solving the model. The beam/shell slice resultants facility is then used to view composite bending moments along the deck. (Version 19.0) Part 2 covers prestress loading assignment.
