Design anchorage length, l_b,d

Enter σ_sd [MPa] or select bar steel grade from list and use nominal yield stress for anchorage length calculation -> 400500600

Bond conditions: Good Other cases

Reinforcement bar stress: In tension In compression

Calculate α-s from bond condition, stress, anchorage type, c_d, p, Kλ and confinement or takes the values from α_i textboxes

Input parameters for calculation type 1:
Type of anchorage: Straight Other then straight (Fig.8.1, b),c),d))


Cover c_d [mm], (Fig.8.3):

Transverse pressure at ULS along ldb, p [MPa]:

Kλ :

Confinement by transverse reinforcement not welded to main reinforcement
Confinement by welded transverse reinforcement, see 8.6
Confinement by transverse pressure


Input parameters for calculation type 2:

α₁ , α₂ , α₃ , α₄ , α₅

For condition (8.5) α2*α3*α5 >= 0.7 check the tooltips for each value!
