Solution

Gross Area The gross area, A_g, of a member is the total cross-sectional area.

The net area, A_n, of a member is the sum of the products of the thickness and the net width of each element The effective net area of tension members shall be determined as A_e = A_nU .

where U, the shear lag factor,
