Ship Structural Analysis
From rationally based design methods to hull-girder loads, member strength, and ultimate capacity of the ship structure.
The course develops a rationally based approach to ship structural design — assessing hull-girder loads, the effectiveness of principal members, and ultimate strength — and connects hydrodynamics with structural analysis through computational work.
Course content
Design methods
- Rationally based ship structural design
- Probabilistic design methods
- Sequential linear programming
Hull-girder loads and response
- Longitudinal strength; still-water and wave-induced shear force and bending moments
- Shear flow, torsional analysis, and warping
- Shear stress lag and effective breadth
Local members and plates
- Bending of stiffened plates
- Large deflection theory of plates and its applications
- Buckling of columns, plates, and stiffened panels; effective width
Ultimate strength and FEM
- Ultimate strength of the hull girder
- Basics of finite element methods applied to ship structures
Learning objectives
By the end of this course, students will be able to:
- Understand the rationally based ship structural design
- Assess the strength of a ship hull girder to still water and wave loads
- Evaluate the effectiveness of hull girder, hull module and various principal members like columns, stiffened plates
- Evaluate the safety and reliability of various levels of a ship structure
- Create a computer program combining hydrodynamics and structural analysis of hull girder loads under the influence of random external wave environment
