d/t > 1.03p(E/Fy)

0.69E/[Fy(b/t)2]

Notes: k: is defined in the footnote of Table 4.4, E is the modulus of elasticity, Fy is the specified minimum yield stress, b is the width of the component element, and t is the thickness of the component element.

TABLE 4.7 Formula for Qa effective area

Q=-acusea^

The effective area is equal to the summation of the effective areas of the stiffened elements of the cross-section. The effective area of a stiffened element is equal to the product of its thickness t and its effective width be given by For flanges of square and rectangular sections of uniform thickness, when b/t > 1.40^/(E/f)a be = 1.91t,./-
