The design compression resistance NRd is given by the minimum of the crushing resistance Ry,Rd, the crippling resistance Ra,Rd and the buckling resistance Rb,Rd of the column web (see Ref.[2], 5.7.3., 5.7.4., 5.7.5)
Rb,Rd is obtained by considering the web as a virtual compression member with an effective breadth beff and buckling length d.
