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.
