Reduction of the design support moment: the value of t
Eurocode 2 part 2: Design of concrete bridge structures 22.214.171.124 (104)
Where specific conditions are met for a continuous beam or slab, the design support moment may be reduced by an amount ΔMEd as follows:
|ΔMEd = FEd,sup t / 8||(5.9)|
where FEd,sup is the design support reaction.
The recommended value of t is the breadth of the bearing.
