v6.3.4

19 September 2024

  • Fixed default resistance factors for LRFD in default/startup files.

  • Resolved input error for CE1 epoxy bars.

v6.3.3

15 August 2024

  • Resolved the issue that caused the input panel to be partially blocked.

...

  • Removed the beta value from the AREMA shear output, as it was not intended to be included.

  • Fixed an error in the C1/CE1 reinforcement input.

  • Bugs related to the support of epoxy-coated mesh bars have been fixed.

v6.3.1

30 July 2024

  • Expanded and revised load factor and load combinations dialog box for AREMA.

  • Added load factor for joint tested boxes (AREMA designs only).

  • Fixed the issue to show additional horizontal and vertical loads correctly in the report for inverted three-sided culverts.  

  • Fixed an issue for ‘Reactions Applied to Structure’ tables results.

  • Fixed an issue that CE1 bar weight was not reported correctly. 

  • Fixed the issue of CE1 bars disappearing from the bar schedule when ‘only epoxy top slab’ was selected.

  • Add support for AREMA group. (dead, live, impact, earth pressure and earthquake), noting that earth pressure refers to horizontal soil loads while vertical soil loads are included in D loads.

  • Fixed an issue that MID - value was not reported correctly for design with span under 5ft.

  • Set default fy to 60 ksi for rebar designs and default earth redundancy factor to 1.000.

  • WSDOT Agency Updates:

    • For top slabs, the minimum thickness should be the maximum of 10”, Table 2.5.2.6.3-1 (Slabs with main reinforcement parallel to traffic), or Article 4.6.2.10.4 (if the length of the culvert is less than 4’). For bottom slabs, the minimum thickness should be 10”.

    • Added a span-to-thickness ratio check per LRFD 4.6.2.10.4 for top slabs.

    • Allowed a 3’ lay length for the short side of skewed boxes.

    • Unchecked the ‘always distribute wheel load’ analysis option.

    • Ensured all 8 seismic combinations are checked.

    • Included Inventory and Operating load ratings in the summary.

    • Added an additional concrete weight to be used for dead load calculations, one for dead load and one for elasticity.

  • ACPA Agency Updates:

    • Updated top cover = 2” 

    • Updated the live load surcharge in the Manual for Bridge Evaluation for rating, reflecting the latest MBE terminology for approaching wheel load. The approaching wheel load can be modeled by a trapezoidal load using the Eq. 6A.10.10.3c-1.

  • Unselected the ‘use eq. 12.10.4.2.4a-1’ option for the NYSDOT agency.
