LEAP CONSPAN v14.00.00.19
Enhancements:
1) 2013 Interim Revisions to the LRFD Bridge Design Specifications are now implemented. The
primary change is phi factors based on strain limits rather than c/dt ratios and support for high
strength steel.
2) A new option has been added to neglect the haunch contribution to section properties
computation is now available. Program will only consider the self‐weight only in this case.
3) Connection to AASHTOWare Bridge Design/Rating (formerly Opis/Virtis) is now updated to
support v6.5.

Fixes:
1)Fixed program crash when working with layout of non‐voided rectangular slabs
2) For flared girder geometry cases, if beams were detected to be laid out non‐continuously,
program prevented analysis from being run. Now only the warning is shown, but user can still
run analysis.
3)Some users reported program crashes when generating Enhanced Report for Positive Envelope
Stresses. Fixed now.

Please let me know if you need any additional information.

Thanks ,

Vinay
