Special topics in steel bridges

Calculation examples are presented throughout the lectures and exercises are given to students during the course:

  • Choice of structural form and concept design of a beam bridge
  • Calculation of shear lag effects in an orthotropic deck and concrete slab
  • Traffic load and fatigue load analysis for a twin girder bridge and for a box girder bridge
  • Buckling of orthotropic plate and deck
  • Global/local interaction in an orthotropic deck
  • SLS stress limitation in bridge with orthotropic and composite deck.

Study Goals
As a result, the student should be able to:

  1. Understand the behavior of many types of bridges incl. movable bridges;
  2. Create and design different types of highway and railway bridges;
  3. Evaluate alternative solutions;
  4. Design bridges by optimal use of steel and concrete;
  5. Understand alternative construction and erection methods;
  6. Understand and calculate ultimate limit state and fatigue loads on bridges;
  7. Perform preliminary design verification of girder bridges according to Eurocodes.
