Wizard A B C This menu brings up the Automatic Bridge Creator ABC Wizard which allows the user to define an entire Bridge including superstructure substructure elements and material information in a simple three stage screen process The following four figures illustrate the information required to complete the definition of a bridge CIP Concrete Pan Girders Reinforced concrete superstructure late 1940 s to present use has faded over last 20 years Span lengths 30 33 ft and 40 ft Very common stream crossing structure Age and short span nature of existing structure may warrant replacement Superstructure Considerations Cast in Place Concrete Pan Girders
At the time of writing this guide 2012 new nonposttensioned connections were being developed 4 2 1 5 Precast Segmental Concrete Superstructure Systems This structural system consists of numerous precast bridge elements that are post tensioned together to form either simple span units or more commonly continuous spans The following thesis presents the results of four full scale beams tests as part of a research program conducted at McGill University The purpose is to study the applicability of existing design provisions in the American Association of State Highway and Transportation Officials AASHTO specifications for the use of self consolidating concrete SCC in precast pretensioned bridge girders
