As a conservative approximation, if t] > 2-^J 1 — ¡5 ,

M,Rd for an I or H section may be assumed to be equal to the design resistance of two transverse plates of similar dimensions to the flanges of the I or H section, determined as specified above.

If t] < 2-^1 — 5 , a linear interpolation between one and two plates should be made.
