Tying systems: the tensile force on internal ties Ftie,int
Eurocode 2 part 1-1: Design of concrete structures 9.10.2.3 (3)
In each direction, internal ties should be capable of resisting a design value of tensile force Ftie,int (in kN per metre width).
Recommendation
The recommended value for the tensile force Ftie,int is 20 kN/m.
