Leap Concrete Bridge Design (de calculation question)

Ashvin Patel — Thu, 28 Oct 2021 14:47:44 GMT

Hi,

I am trying to design prestressed concrete 78" Girder with 8.25" Slab thick. my Prestressing steel centroid is Ypg=9.88 in and total section height H=86.25"

so my dp=H- ypg=86.25-9.88=76.37". I have no mild reinforcement in the girder, so dp=de. The program is calculating de to be 83.03", and i would like to know why the reason for that?

Per AASHTO 9ed

Thank you

Ashvin

Has Bent with 3 Columns with Footing on Piles.

Program requires to run Column design before Cap design. After column design try to run Cap auto design, it starts and then terminate abruptly. Tried LRFD normal, 2015 interim, 2016 interim and 2018. All has same behavior.

Any suggestions?
