• ACI 318-19

  • The user can now specify if design should follow ACI 318-14 or ACI 318-19 on the Design Criteria tab under Specification.

    • This option changes many calculations. To summarize the changes in more detail, see the page ACI 318-19 Changes.

• New analysis option for confinement factors for mild development length of bars with hooked or headed ends.

  • This option behave slightly differently depending on if ACI 318-14 or ACI 318-19 are being used. More information can be found on the documentation for the option.

• New load pattern selector

  • New options can be found throughout the Analysis Report which can be used to specify which load combination / load pattern should be used for the corresponding output.

    • These options allow the user to user use the worst case or specify the following:

      • Load Combination

      • Live Load Case

      • Wind Load Case

      • Seismic Case

      • Location on Beam (when applicable)

    • The options can be found on at the following sections throughout the output:

      • Strength Results

      • Service Results

      • Detailed Flexure

      • Horizontal Shear

      • Camber and Deflection

• Report Optimizations

  • The time required to refresh the output has been drastically reduced. This should result in a faster analysis time and make the output more smooth when navigating.

• Torsion Output

  • Torsion tables have been reworked for all three torsion methods. This should make it easier to determine where transverse reinforcement is required for non-symmetric torsion methods (like slender spandrel).

  • A new section has been added below the Shear and Torsion table called "Plate Bending at Supports"

    • This section is only active if Zia-Hsu or Slender Spandrel are being used for the torsion methodology. This section shows the requirements of the plate bending at the centerline of supports separately from the general torsion check. This is because these computations, as defined in the PCI Design Handbook, result in a minimum amount of transverse reinforcement being required within a set distance. Previously we just divided this requirement by the zone length, but this can be conservative and make it hard to optimize the transverse reinforcement design.

• Detailed flexure summary now displays the 'd' computation for tension bars, compression bars, and prestressed reinforcement.

• Shear steel requirement graph now includes Av minimum when required.

• Miscellaneous improvements and fixes
