Virtis bridge rating

Yesterday I started to learn AASHTO's bridge load rating software "Virtis". I used the program to rate a bridge for an off ramp on I-95 in Providence. So far I have only finished the exterior plate girder in Span #1 of a 3 simple span bridge.

Hopefully soon I will be able to use this program more and with more confidence. In the next three months we have approximately 20 bridges to rate and so far I am currently working on 4 ratings for Rhode Island and a 3 mile long highway foot print reconstruction project in Southbridge, MA.

The drainage which I have been assisting with is almost complete and the calculations are about 130 excel sheets long.
