Viaduct expansion pier location/distances
Viaduct expansion pier location/distances
(OP)
Good Day!
I am designing a 21 span viaduct (with aashto girders). Where should I put the expansions? I'm assuming that that there should be expansions when the girder type changes. My basis is AASHTO LRFD 2012 but I can't seem to find expansion piers in the code.
Thanks!
