LRFD Braking Force
LRFD Braking Force
(OP)
Good morning -
When designing a pier for a two span continuous structure, the controlling load for the vertical reaction is a lane load with TWO design trucks (one in each span).
When computing the BRAKING FORCE, do you use the axles for a SINGLE truck or the TWO trucks?
It is my understanding that the BR is computed using only the SINGLE truck.
Thank you.

Look at the load combinations and evaluate each of them for 1 lane, 2 lanes, etc.
