PRESTRESSED BRIDGE BEAMS Description
An app for engineers to determine bridge stresses for post-tensioned T beams and for pre-tensioned M beams. Stresses are calculated at two stages namely, at stage 1 transfer stage of only the precast beams simply supported non-composite and stage 2 with service loads of continuous composite section of precast beam and slab. Calculation of stresses are based on British Standard 5400 Part 4: 1990 Steel, concrete and composite bridges Part 4: Code of practice for design of concrete bridges.
