Based on the recommendations of EC 3, part 5 the values of the tensile resistance Ft,Rd and the axial force of the anchor under characteristic loading Ft,ser have been calculated by using the partial factors YMO = 1,0; YM2 = 1,25; and YM3, ser = 1,1. The partial factor Kt = 0,6. As/g is the tensile stress area of the threaded portion or the gross cross-sectional area of the shaft, whichever is smaller.
The calculated tensile resistance is:
- Ft,Rd= MIN (Ftt,Rd ; Ftg,Rd).
- Ftt,Rd= Kt * fua / YM2.
- Ftg,Rd= Ag * fy / YMo.
The axial force of the anchor under characteristic loading:
- Ft,serÔëñ fy * As/g / YM3,ser.
