Other verifications of fatigue: the value of k3
Eurocode 2 part 1-1: Design of concrete structures 6.8.6 (3)
Where welded joints or splicing devices are used in prestressed concrete, no tension should exist in the concrete section within 200 mm of the prestressing tendons or reinforcing steel under the frequent load combination together with a reduction factor of k3 for the mean value of prestressing force, Pm.
Recommendation
The recommended value of k3 for this fatigue verification is 0,9.
