| Abstract: | The lateral stability of stringer flange of stiffened panel under axial compressive loading was studied. Combined the design factor of strength and stiffness of stiffened panel, the lateral buckling critical load of stringer flange was analyzed, and the calculation method of stiffness design criterion of support sheet of stringer flange was proposed. The method can provide some guidance for the engineering designers to improve the design efficiency. |
