The course is immediately follows the course "Costruzioni Navali B" and represents its natural continuation in terms of content. The student accesses the course with basic skills about the scantling of boats, which allows him to make design choices using highly simplified methods. The course intends to deepen the structural models to provide the student with the necessary skills to develop more refined scantling methods.
At the end of the course the student will be able to: Carry out a preliminary structural design of the yacht. This includes demonstrating understanding of the main structural loads acting on the ship's primary, secondary and tertiary structures. Apply the concepts of ship beam to the hull. Apply the basic concepts of shear stresses on primary and tertiary structures. Carry out instability checks on the plating.
The course deals, in detail, with the description of the types of stresses originting in a yacht starting from internal and external loads. The hierarchy of tensions will be widely described, as well as the effects of each stress component on structural elements will be taken into account for the purposes of scantling, also showing scantling methods able to consider the effects of combined stresses..
The teachings of building science are fundamental for understanding the topics presented along with the lectures, as well as the contents of courses of "Costruzioni Navali"A and B.
Frontal lecture with application exercises supported by spreadsheets (excel).
Calculation of primary stress characteristics (hull girder)
Scantling of local structural elements according to combined stresses (primary and tertiary)
Structural grilliage and secondary response estimation
Limit states (fatigue, buckling, ultimate state)
Notes on torsion (dimensioning of the axis line)

All class schedules are posted on the EasyAcademy portal.
Written test where the student will be asked to solve one of the structural problems presented during the course, followed by oral exam.
The written test aims at verifying the student's ability to solve a practical problem of structural santling, according to the methods presented during the course. The oral exam is aimed at verifying the learning of the theoretical bases on which the scnalting methods are based.
