Detailed description of topics:

The course places the structural design within the context of the overall design of ships and offshore structures. The history and background of the field is put in the perspective of further development.

The principles of the conceptual design of the structure are treated, starting with the structural tasks. Structural strength and stiffness has a (quasi-)static as well as dynamic nature, can be considered deterministic as well as probabilistic. Economic and fabrication considerations can restrict the design.

The behaviour of beams and plate, stiffened or non-stiffened, gives the elements for further analysis of the structure. Various loads are possible and determine the responses, leading to a variety of failure modes. Different ways of modelling the structure to allow numerical analysis are possible. Each has its pros and cons. The connection between various structural elements and substructures is important. So are the materials to be used.

Remarks (specific information about assesment, entry requirements, etc.):
The course is accompanied by a set of experiments in the Ship Structures Laboratory.

Goals:
The course is designed to provide all future naval architects with sufficient insight in the design and behaviour of ship and offshore structures, to teach them to make an optimal conceptual design, to teach them the impact of material properties, fabrication and other limiting factors. The students will learn the more important structural analysis methods.

Computer use:
No computers are used in the course itself. A CAD-system is used for scantling determination in the design of a midship-section.

Laboratory project(s):
In the Ship Structures Laboratory the students are trained in determination of material properties and in measuring stress distribution in a plate. See mt827 d2

Design content:
The course addresses the (structural) design of ships and offshore structures. About one quarter concerns conceptual design, the remaining part concerns response analysis and the impact of other factors on the design.

Percentage of design: 75%
