CSiBridge Loading
Latest release: CSiBridge 15.2.0

Vehicles

  • Auto transfer of vehicle loads to bridge structure
  • Extensive vehicle library including AASHTO and other codes
  • Fully customizable vehicles

Vehicle Classes

  • Vehicle classes are sets of one or more vehicles that can be assigned to act on lanes in a moving-load case.
  • Only one vehicle in a class acts on the lane at a time. Results are reported for the vehicle causing the most severe response.

Load Patterns

  • Unlimited number of load cases and combinations
  • Automated design combinations based on selected design code
  • Strength and service combinations
  • User-defined load combinations
  • Linear add, envelope, absolute add, SRSS, and range combinations

Load Combinations

  • Automatic permutation of Wind directions and eccentricities
  • CSiBridge will automatically generate wind loads based on various domestic and international codes including but not limited to:
    • UBC 94; 97
    • BOCA 96
    • ASCE 7-95; -02; -05
    • NBCC 2005
    • Mexican
    • Chinese 2002
    • IS875 1987
    • User defined
  • Open Structure Wind Loading

Parametric Loading

  • Superstructure loads may be defined and assigned to a bridge object model parametrically. 
  • Bridge Object loads may be assigned for any defined load pattern type and may include loads due to wearing surfaces, parapets, forms,  diaphragms, girders, decks and more.  
  • Once the parametric bridge object loads have been defined they may be easily displayed and modified. 
  • Parametrically defined load assignments are preserved even when changes are made to the bridge object discretizations, deck types or alignments.
