User Interface


  • user interface is a Microsoft Visual Basic tabbed dialog with 15 tabs including 3 for Geometry, 2 for Properties and 6 for Loads
  • the dialog is filled from the Workbook identified in the Load button procedure
  • path of file may be defaulted to simplify loading of files
  • analysis and output is implemented on Excel Workbooks, one per project
  • older version workbooks can be easily imported into the current version

File Tab

Geometry 1

  • used to specify Superstructure and Abutment design parameters
  • each span can be entered as an independent Superstructure Type
  • Continuous or Non-continuous Abutments are defined by simple selection
  • the Geometry 2 tab is for Pier design parameters
  • the Geometry 3 tab is for Live Load Girder Distribution parameters

Video Tutorial

Geometry 1 Tab

Properties 1

  • used to input the Superstructure design parameters
  • different design parameters for each span may be specified
  • spans with identical design parameters may be grouped to simplify data entry
  • the Properties 2 tab is for the properties of the Abutments and Piers

Video Tutorial

Properties 1 Tab


  • used to input Construction Stage Loads, Dead Loads, and Superimposed Dead Loads
  • only one entry required to generate pattern loading during construction
  • pre-designated typical load cases that may be edited
  • Loads 2: - Load Case Grouping Alternatives (enables designs up to 30 axles) and associated Truck Spacing
  • Loads 3: - Truck Loads per Lane and Axle Spacing
  • Loads 4: - Thermal Data for Superstructure and Soil Pressure Data
  • Loads 5: - Shrinkage & Creep and Prestressing Creep

Video Tutorial

Loads 1 Tab

Loads 6

  • used to input Vertical Wind Pressure and Differential Settlement Loads
  • used to simplify data entry by copying Loads from span 1 to remaining spans if applicable.
  • Vertical Wind Load over each span based on deck or superstructure width is automatically generated
  • only single load entries required for Vertical Wind and Differential Settlement;  generation of pattern loads is performed automatically

Video Tutorial

Loads 6 Tab


  • used to specify the number of increments analyzed and reported per span and support
  • used to view calculated values for locations between the increments reported in the results tables
  • used to simplify printing of the results tables (up to 135)
Analysis Tab

Combinations 2

  • calculates max/min combination envelope results for all comparable limit states conditions without generating individual combinations first
  • user defined or CSA-S6-S14 load combinations
  • user defined or CSA-S6-S14 load amplification (distribution) to Exterior and Interior design strips or girders
  • user defined distribution of loads to substructures
  • generates combination for loads on naked girder or composite girder using one model
  • the Combinations 1 tab gives the user total control to calculate any individual combination of interest

  • conformance with the Canadian Highway Bridge Design Code CSA-S6
  • simple and minimal tabular input of structure model and loads for continuous beam, rigid and integral abutment and pier analysis
  • model trucks or vehicle patterns with up to 30 axles
  • named bridge member components rather than numerically identified members
  • simplified and automatic generation of support conditions
  • automatic generation of compression only horizontal reactions to simulate backfill behind abutments acting as supports
  • automatic generation of composite section properties
  • only one model required for all load conditions and construction stages
  • automatic generation of soil pressure relative to temperature expansion and contraction of superstructure for frame bridges
  • automatic patterning of loads such as construction, wind, and differential settlement
  • automatic application of all loads
  • all loads input as positive values except temperature below zero
  • pre-designated load cases that may be edited
  • User requested automatic generation of second and/or third span properties and loads, to match first span input
  • truck axle loads not contributing to the maximum load effects are automatically eliminated from the analysis
  • automatic generation of governing live load effects (truck loads vs. lane loads)
  • differential shrinkage and differential temperature effects between the girders and deck
  • restraint moment load effects from prestressing creep, dead load creep, and shrinkage effects
  • output is very clearly defined
  • output of results is left to right for superstructure and top to bottom for substructure, not dictated by order of input typical of general structural programs
  • User can obtain results at any location on structure without reanalyzing
  • live load moment, shear, and axial distribution factors for Type A, B, C, and D(a) bridge types as per Table 5.1
  • distribution factors for governing interior and exterior girders in positive and negative regions of continuous frames
  • generation of load combinations and application of Loads to Interior and Exterior design strips
  • output is in Microsoft Excel making it very accessible for viewing and generating graphical output
  • longitudinal effects from braking and earthquake loads
