Description
Technical Field
The invention relates to the technical field of hull structure design, in particular to a structural style for improving the total longitudinal strength of a large-opening area on the lower side of a steel marine strong deck.
Background
Because of the general arrangement, the large openings of the steel sea vessel are needed on the outboard side outer plate below the strength deck, which can result in the outboard side outer plate reducing the shear force transferred to the strength deck, reducing the effectiveness of the strength deck and its longitudinal continuous members within the opening below. Particularly, if the large opening is positioned in the range of 0.4L in the ship, the area where the large opening is positioned needs to bear relatively large total longitudinal bending moment, and the structural safety of the ship is more challenging.
In order to solve the risk of the large opening to the overall longitudinal strength of the hull beam, the conventional design is to strengthen the strength deck, such as thickening the strength deck plate, and increasing the size of deck stringers and stringers. But this reinforcement has little effect on the overall longitudinal strength of the hull girder in the large open area and is at a great weight cost. Therefore, the conventional design of the hull structure in the large opening area needs to be changed, and a new structural type is proposed to improve the overall longitudinal strength of the hull beam in the large opening area.
