About the information displayed by the Auditor

The Auditor display information for a single cross section of one span segment strip, or a design section.

The Auditor displays the following:

  1. Design strip and cross-section number, or design section number
  2. Concrete components for a cross section
    • number of concrete blocks
    • top and bottom elevation of each block
    • depth and width of each block
    • initial and final strengths (cylinder and cube)
    • initial and final Ec (modulus of elasticity) values
    • density
    • inclusion or exclusion of block from shear core
    See "Concrete "Core" Determination" for discussion of shear core.
  3. Reinforcement properties for each bar type
    • elevation
    • yield stress
    • Ec (modulus of elasticity) value
    • bar area
    • bar diameter
  4. Tendon properties for each tendon type
    • elevation of cgs (center of gravity of strand) above datum
    • ultimate strength (stress)
    • yield stress
    • effective stress
    • Ec (modulus of elasticity) value
    • area of strand
    • bonding
    • R-component [the component of the tendon parallel to the design strip cross section (perpendicular to the design strip spine)]
    • S-component [the component of the tendon perpendicular to the design strip cross-section (parallel to the design strip spine)]
    • Z-component [the vertical component of the tendon across the cross-section (only used for hyperstatic calculations)]
    • length
    • initial concrete strain
    • duct width
    • number of strands per duct
    • cross sectional area per strand
    • number of ducts
  5. Base design envelopes (for each Rule Set Design):

    The envelopes for maxima and minima of moment and shear force are displayed. These are modified, as appropriate, for torsion and axial force design. The envelopes list the following resultants:

    • Vr (horizontal shear)
    • Ps (axial tension)
    • Vz (vertical shear)
    • Mr (bending)
    • Ts (torsion)
    • Mz (diaphragm bending)
  6. Reinforcement (for each Rule Set Design):

    Depending upon the rule set, RAM Concept adds reinforcement to the cross section.

    • As Top
    • As Bot.
    • As Shear Density
    • As Shear Spacing
    • As Shear (density multiplied by spacing)
    Brackets appear after each result showing which code rule governed.
  7. Cross Section Forces (Analysis)

    Depending upon the rule set, the Auditor displays cross section forces and other information.

    • Cross Section Strains
      • curvature
      • top, centroid and bottom strains
    • Concrete Forces for each block
      • top and bottom stress
      • force
      • force elevation
    • Untensioned reinforcement forces for each bar
      • elevation
      • strain
      • stress
      • bar area
      • force
    • Post-tensioning forces for each tendon
      • elevation
      • cross-section strain
      • component cross-section strain (considers tendon angle)
      • Tendon Force (effective force in cross section plane)
