A Discussion of Limited Loading Ability of Square Plate

Li Changchun; Shi Depei; Wang Bocheng(Department of Naval Architecture and Ocean Engineering)  
The elastic and plastic method is often used in designing the inner flat bulkhead plates of submarines, and the upper structure of ships and drilling platforms. Such bulkhead plates can underload only once. In order to improve the underloading ability or to reduce the weight of plates, the yield line analytical method is employed in this paper to design the prementioned bulkhead plates to improve economy and increase the loading efficiency. Besides,a further probe into this method has been made theoretically and experimently, and the data of the limited underloading ability of the plate is obtained. Furthermore, the safety coefficients of such a method are presented, which can be used as reference for associated departments and stuffs.
