AASHTO 4.6.2.1.3 - Width of equivalent strip for the Design Tandem
(OP)
Hey all,
I'm a bridge EIT stuck on a little deck design question that I can't really find explicitly said anywhere in AASHTO (or anywhere else online).
If the entire design tandem is to be included in the deck design it presumed to be distributed over a larger equivalent strip. Is this strip supposed to be double the strip width calculated by 4.6.2.1.3, except for in the case of overlapping strips where it would become the width of one strip +4ft (tandem axel spacing)?
Thanks! (Bridge Forum is a bit of a wasteland)

The only time I account for the overlap is calculating the wheel load pressure that is being distributed to a RCB.
