v6.0.0

26 Sep 2022

• New Features:

  • WSDOT agency

  • Ability to calculate EH loads through the following methods:

    • Soil equivalent earth pressure (used in all designs prior to v6.0.0)

    • Active earth pressure

    • At-rest earth pressure

  • Ability to model culvert on flexible foundation

  • Allow user to select ASTM steel for automatic calculation of gamma factor 3 (on Material Properties window)

  • New options for when the effects of LL can be neglected

  • New options for how vertical and horizontal seismic forces combine

  • Allow users to define free-field ground strain for the seismic analysis

  • Allow both internal and external water to be analyzed in the same design

  • Allow the input of negative pressure heads

  • Added new option to epoxy all steel in top slab

• Bug Fixes:

  • Corrected reported midspan deflection, for cases when 1/9999 was displayed

v5.14.0

06 May 2022

• New “type III” culvert type (joints at both top and bottom of walls)

• New optional “design limits” on Project Settings window

  • Note: this will only alert you if your design exceeds these input limits, it does not effect the auto-design algorithms.

• New analysis option to include approach slab

  • Note: if this is selected, live load surcharge will be neglected

• New option for users to define the free field displacement in the seismic analysis

• New option to apply horizontal loads at the top of the walls to inverted three-sided culverts

• Added ability to define additional analysis points

• Allow more letters for designer name

• Corrected bug in which impact factor could not be input if using the CHBDC design specification

• Corrected conservative units error in calculation of exterior water pressure

• Misc. interface improvements
