OVERVIEW

The course has the aim of giving the students the tools to critically carry out the dimensioning of the main ship structures built both in aluminium and steel and composite materials. Starting from the physics of the problem, the students will be driven to the crtical comprehension of rules and requirements.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the specific knowledge for the identification and evaluation of the loads on the hull structure and the realization of a homogeneous structural scheme able to withstand these loads and compatible with the constraints imposed by the hull and the shape and distribution of functional spaces .

AIMS AND LEARNING OUTCOMES

Successfully overcoming the course the students will be able to:

• apply the theory of building science to naval applications
• analyse and synthetize the loads acting on the different types of boat structures
• critically apply the main rules and requirements
• understand the main structural drawings
• understand the main pros and cons of the different types of material mainly used in boat construction
• autonomously carry out the design of the main structures of boats

TEACHING METHODS

The course foresees both theoretical lectures and computer exercises. In particular with the help of a spreadsheet the main structural checks will be implemented for the structural design of yachts.

SYLLABUS/CONTENT

• Introduction to the course, categorisation of loads, main types of structural failures
• Recall of the Eulero Bernoulli beam equation
• Exercise: calculation of the main geometric characteristics of beam cross-sections
• Recall of the Virtual Work Theorem
• Exercise: calculation of the main geometric characteristics of a ship main section and steel weight distribution
• Rigorous solution of the built-in beam loaded with uniform load
• Structural hierarchy, supported area concept, schematisation of panels as unitary beams
•  Exercise: calculation of stresses distribution along the cross-section of typical beams
• Direct scantling of the sides and the bottom of a boat built in composite
• Shear design for sandwich structures
• ISO norms for the structural design of yachts
• Exercise: implementation of a spreadsheet t for the application of ISO rules
• RINA Pleasure rules for the structural design of yachts
• Exercise: implementation of a spreadsheet for the application of RINA rules
• Compilation of the lamination table

EXAMS

EXAM DESCRIPTION

The exam is both written and oral. Three calls are foreseen in the summer session (June, July and September) and in two in the winter session (January, February)

The written part foresees  the solution of an statically indeterminate, the scantling definition of a typical boat structure. The oral part will focus on the written exam discussion, on the discussion of the exercises developed during the course and on the whole course contents.

ASSESSMENT METHODS

The candidates must enroll at least three days before the exam data on the informatic system.  the results for the written part will be published on the AUlaweb portal together with the oral date.

No enrolment is needed for the oral part.
