The objective of this study is to develop a procedure for predicting the nonlinear bending behavior of the nailed stressed-skin component. This component might be regarded as a kind of nailed layered beam. When it is subjected to external loads, the direct forces in the plane of the plate are not uniformly distributed over the width of the plate. Because of this, the analytical procedure for predicting the nonlinear bending behavior of the nailed layered beam developed in the first part of this study is not applicable directly to the component. However, to use the concept of the effective breadth, assuming uniformly stressed width, instead of the actual width of the plate makes the procedure applicable to the nailed stressed-skin component. In other words, the component can be regarded as the nailed layered beam with the effective breadth. The effective breadth is obtained by Amana and Booth's theory (1967a, b). The experiments that were conducted to examine the validity of the procedure showed that it gave excellent agreements with the experimental results. The solution was used for investigating the effect of some parameter on the stiffness, and useful information for designing the component was given.
