Syllabus
This course is full of best-in-class content by leading faculty and industry experts in the form of videos and projects
Course Overview
- This is a specialist course on reinforced and prestressed concrete bridge structures.
- The course exclusively focuses on bridge superstructures.
- Most modern concrete bridge forms such as solid and voided slabs, ribbed decks, prestressed girders and box girders are covered.
- The course also touches on the steel-concrete composite design.
- Various analysis techniques are explained using hand calculations, struct and tie models and computer-based FEA models with both grillage and shell elements.
- Advanced topics such as long-term effects, integral bridges and construction stage analyses are included in the course.

Week 12 - Construction Stage Analysis
- In this session, you will learn about
- Various ways in which concrete structures can be constructed, e.g. cast-in-situ, launching and balanced cantilever construction
- The design can often be governed by the construction schedule, and structures should always be verified in their temporary state
