Can anyone share the equation or any source to calculate the VRd, max & VRd for the foundation resistance calculation as per attached image(Eurocode 7), please.
Could anyone shed any light on the k1 factors given in formulas 6.2.a and 6.47 of EN 1992-1-1. For shear in a beam k1=0.15 and for punching shear k1=0.1, these factors obviously have quite an effect on the shear and punching shear resistance of prestressed members. Does anyone know of any experimental evidence or papers explaining the reasoning behind these large factors??
