Actions during execution: the wind pressure acting on one cantilever x
Eurocode 2 part 2: Design of concrete bridge structures 113.2 (102)
For the ultimate limit state verification of structural equilibrium for segmental bridges built by balanced cantilever, unbalanced wind pressure should be considered. An uplift or horizontal pressure of at least x N/m2 acting on one of the cantilevers should be considered.
The recommended value for the wind pressure of is 200 N/m2.
