E – 1890 Steel Bridges – Designing for Constructability

In many cases, bridge designers concern themselves only with checking the stability and member stress levels in the structure for the in-service condition after erection of the entire superstructure is complete. But many times the critical stress in a particular component is encountered during the erection of the bridge where large unbraced lengths affect the stability of the partially completed structure.

This course describes typical erection methods and procedures and highlights some of the aspects that should be considered by the designer. With this basic knowledge, the bridge designer can determine which, if any, of these aspects are a concern for his/her particular design situation.
