Outer wing connects center wing by butt joint rib, which web transfers the load from wing and provides the support for structure. With the development of manufactures, integrated rib stiffened web which is different from the traditional assembled web was employed on the advanced civil aircraft. . Based on Hyperworks (finite element software) to uniform fuel pressure combined with compressive-shear force, two webs were compared on performance under deformation, local buckling, global bucking and failure and the stiffener location were obtained. Compressive-shear force experiment results were analyzed, and emulation was validated. The research can support the part design in the key joint area.
