This paper presents the theory used to implement in the LBR-5 software an analytical solution of the stiffened panels governing equations. For that purpose, Fourier series expansions are used to solve the governing differential equations. In the present analysis, cylindrical shells are used as the reference panels. Stiffened plates are considered as a simplified case of the more general cylindrical shell. In the LBR-5 software, plates are analyzed as being cylindrical shells having a very large radius (q = 10) m). The present method has been developed for fast and accurate linear elastic analysis of stiffened structures, particularly in regard to structural optimization. The LBR-5 software is after15 years now well established and patented. Its application to ship structures including its associated background about the scantling optimization procedure is well known from various papers and conferences.
