NP 45: Values CRd,c, vmin and k1, which are used in state may be found in national annex.
Recommended value for CRd,c is 0,18 / gc, for vmin is defined by formuls(6.3N) and for k1 is 0,15.
NP 47: Limit values cot q, which are used in state may be found in national annex. Recommended limitations are defined by formula 1 < cotq q < 2,5.
Coefficient aI (equation 6.4):
- aI = lx/lpt2 < 1,0 for the prestressed reinforcement
- aI = 1,0 for other kinds of prestressing;
