Analysis of the Effectiveness of Superstructure

How to contribute to the hull girder strength for the superstructure,namely,the superstructure effectiveness is often considered on the design of ship structure.Correct calculation of superstructure effectiveness can not only help the structure design of superstructure,but also avoid the appearance of cracks and extend the service life of ships.On modern project design,various approximate methods are used to estimate the superstructure effectiveness.The precision and applicability of these methods should be validated with experiments.The guidance to the project design is to come true.
