Research Abstract

This study is concerned with the reliability assessment of combined plate and beam structures based on collapse mode analysis. Results obtained in this study are summarized as follows :
1. A new plate element is developed for efficiently and accurately analyzing thin walled structures such as marine structures composed of many stiffened plate panels with initial imperfection, using selective eigen-functions for large deflection and sectional yield conditions.
2. A new system using combined plate and beam elements is presented to offer the expansion of the applicability of the structural reliability-based sensitivity analysis combined with collapse mode analysis.
3. The applicabiity of the proposed system is demonstrated through a numerical example applied to a simple box girder with longitudinal stiffeners.
4. Features of the structual reliability and sensitivity factors of a high speed container ship under heading and oblique sea conditions are also investigated by applying the newly developed system.
5. The analytical result, e.g., for the aft L/4 part of the hull structure under the oblique sea condition shows that effects of in-plane shearing stresses due to torsional moment on the dominant collapse mode including damages of the middle part of the inside shell elements are dominant. These features are good correspondent with results in previous researches.
