Design values for the compressive stresses within nodes: the values of k1, k2 and k3
Eurocode 2 part 1-1: Design of concrete structures 6.5.4 (4)
The design values for the compressive stresses within nodes may be determined by:
a) in compression nodes where no ties are anchored at the node
σRd,max = k1 ν' fEcd | (6.60) |
b) in compression - tension nodes with anchored ties provided in one direction
σRd,max = k2 ν' fEcd | (6.61) |
c) in compression - tension nodes with anchored ties provided in more than one direction
σRd,max = k3 ν' fEcd | (6.62) |
Recommendation
The recommended values of k1, k2 and k3 for the calculation of the design compressive stresses within nodes are k1 = 1,0, k2 = 0,85 and k3 = 0,75
