Steel Bridge Erection Practices

This synthesis report will be of interest to all individuals involved in the steel bridge industry. It examines, discusses, and analyses steel bridge erection practices for continuous and simple I-girder, tub-girder, and box-girder bridges; particularly curved, skewed, and staged structures. Key topics considered included the impact of design and analysis practices on erection; methods used to predict erection deflections as a function of bridge type and complexity; shop-assembly practices and alternate methods of ensuring properly assembled geometry; stability issues; field connection practices; examples of structures in which erection practices have caused problems; owner requirements for erection procedures, implementation of requirements, and the impact of procedures on the quality of erection; and current and proposed research.
