AASHTO Bridge Deck Design

AASHTO Bridge Deck Design

AASHTO Bridge Deck Design

I'm trying to find a worked example for AASHTO Bridge Deck design.
Every example I have references AASHTO A4-1 table for the live load effects. This would be fine for the majority of deck design situations but I need to check some special permit trucks to ensure that I'm not underdesigning the deck.
I want to make sure I'm applying the truck loads properly. Thank you in advance.

RE: AASHTO Bridge Deck Design

Look at Section of AASHTO LRFD including commentary for what loads to consider for deck design. I have not designed a deck for permit loads and I have not come across a bridge owner agency which requires that.

RE: AASHTO Bridge Deck Design

Thanks EQguys. HL-93/Tandem is still expected to control but this particular official simply wants to go the extra mile due to the increased permit truck volume from a neighboring state. They want to check the load effects of this permit truck that's not included in their own Bridge Manual. I would be more comfortable if I had a worked example to check the procedure against my calculations.

RE: AASHTO Bridge Deck Design

Thanks Bridgebuster, I used both those detailed examples to prepare my calculations. The FHWA example used AASHTO A4-1 and Caltrans used its own proprietary software to generate the live loads. I was interested in seeing an example where a permit truck was applied to generate the live loads and whether there was any specific guidance there, but it appears most jurisdictions just ignore it altogether based on industry consensus.
