Eq.

(6.20) is then applied to determine the ULS of the stiffened panel, but with membrane stresses given by Eq. (6.

31). This orthotropic plate theory has also been added to ALPS/ULSAP (2006) for the Mode I ultimate strength calculation of stiffened panels..

By using the Airy stress function, the stress components at a certain location inside the panel may be expressed as follows: x = y = 2 F Ez 2 y 1 2 2 F Ez 2 x 1 2 2 w 2 w + 2 , x 2 y 2 w 2 w + 2 , y2 x (6.

(6.32) does not re ect local buckling of stiffener webs (Mode IV) or tripping of stiffeners (Mode V), but these equations can be used to accurately analyze for the elastic large de ection behavior for Modes I, II, and III.

These equations can be solved directly under applied loading and boundary conditions, for example, using the Galerkin method. Again, once the membrane stresses inside the stiffened panel are calculated, the panel ULS can be determined applying Eq. (6.

28). 6.6.

4 Semianalytical Methods A method, similar to that described in Section 6.5.4 for plates, can be applied to solve the governing differential equations, Eq.

(6.32), for stiffened panels (Paik and Lee. Ultimate Limit-State Design 2005). First, it is assumed that the load is applied incrementally. At the end of the (i 1)th step of load increment, the de ection and stress function can be denoted by wi 1 and Fi 1 , respectively.

In the same manner, the de ection and stress function at the end of the ith step of load increment are denoted by wi and Fi , respectively. Therefore, the accumulated (total) de ection wi and stress function Fi at the end of the ith step of load increment are calculated by wi = wi 1 + Fi = Fi 1 + w, F, (6.34a) (6.

(6.22), the incremental forms of governing differential equations, Eq. (6.
