Can LEAP RC-Pier analyze/design for a cantilever abutment?

I used RC-Pier for Abutment Cap with Pile Design before, but not sure if it works with cantilever abutment design.

Thanks

LEAP Bridge Concrete v16.01.00.10 - Substructure - Can Pier have a tapered cap and have a off-set column?

I try to create a pier with a tapered cap, which is unsymmetrical and with a column near one edge.

Is it possible? I know i can create a symmetrical cap with a column offset from the center, but the location of non-tapered segment cannot be modified.

Thanks

LEAP Bridge Concrete Connect edition v16.1.0.10 - Which AASHTO edition is using?

I use LEAP Bridge concrete (v16.1.0.10) and its Substructure (RC-pier) to run an abutment design. The analysis result output stated it is using "AASHTO LRFD 7th with 2015 Interim" in the beginning.

1) However, a note right after "Flexure Design" stated "CL: Section classification as per LRFD 2006 Interims for provided reinforment."

2) Also, for "Cracking/fatigue check", it stated "Cracking check as per AASHTO LRFD (6th edition, 2012).

The project I am working on needs to use AASHTO LRFD 7th with 2015. Can someone verify if it is a description issue or LEAP is really using older version for those section?

Thanks a lot

Alex
