Precast/Prestressed Girder Help

Design

  • Customize or select limiting stresses for concrete at release and final conditions.
  • Customize or select length multipliers for transfer and development lengths.
  • Automatically generate straight and draped strand patterns or manually input the pattern for analysis.
  • Specify transformed section properties.
  • Customize the maximum number of strands that can be debonded, as the maximum percentage of each row, or the total number of strands in each section.
  • Specify end and midspan debonding (shielding) manually or have the program compute it automatically.
  • While using a draped/straight pattern, only the straight strands can be debonded.
  • Customize varying percentages of strand pull for various strand groups.
  • Copy beam strand patterns to other beams in same span or other spans.
  • Retains previously designed strand patterns when changes are made to geometry, materials, or loads information.
  • Specify or have the program compute release and final prestress losses according to the CHBDC Specifications.
  • Optionally compute Moment Capacity by Strain Compatibility.
  • Automatically design top flange tension reinforcement at release.
  • Check design status at critical points for release and final stresses as well as for ultimate loads and cracking load criteria.
  • Perform vertical, anchorage zone, and horizontal shear reinforcement design.
  • Optionally, input Stirrup reinforcement schedules manually or use auto-design algorithms.
  • Store commonly used stirrup schedules and prestressed strand patterns (including debonding and pull percentages) in the library file, and reuse across projects.
  • Automatically compute deck reinforcement required for continuity.
  • Specify Negative Moment Continuity steel in deck slab. Compare required vs. provided capacities.
  • Report camber and deflection computations at tenth point locations along the beam, including live load deflections.
