ABSTRACT
The structure considered in this example is a twin-girder composite bridge, with a standard configuration for this type of structure. It is taken from guidance produced by SETRA [19.1], adapted to the principles of design covered in this book. The example bridge has a simple geometry (the bridge is straight and without a skew), which limits the complexity of the calculations. Following a description of the bridge, its use and the materials adopted, one way to carry out the preliminary design will be shown in Section 19.3.
