d/t > 1.03p(E/Fy)


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


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,./-
