    PSC Bridge Design with OBM / RM in Standalone workflow

     In the following example a three-span concrete hollow box girder shown in the picture below will be defined. The bridge is built in three construction stages.

     

     

     

    The 140m long three-span bridge (40m + 60m + 40m) is located on a circular curve. The cross-section of the main girder is hollow box and varies along the station. The substructure consists of two 20m tall piers and two abutments.

     

    Procedure and main features for PSC Bridge Design:

    • Construction stages with change in elements, boundary conditions and loading.
    • 3D tendons placement assignment.
    • Creep and shrinkage calculations following the standard codes.
    • Time dependent steel relaxation.
    • Cross-sections displayed to true shapes.
    • Generation of tapered sections (change in thickness of top/bottom flange and webs with independent variables).
    • Effective width introduced with variables.
    • Stress state checked for final and in constriction stages.
    • Eurocode 2, AASHTO LRFD and other standard codes.
    • Cracking control with reinforcement calculation.
    • Ultimate bending capacity check.
    • Shear and torsion strength checks.
    • Perform reinforcement layout for drawings production.
