OVERVIEW

The course generalise the concept of structural design from a deterministic to a probabilistic viewpoint: compliance to requirements is assessed on the basis of the probability of crisis and, possibly of consequences

AIMS AND CONTENT

LEARNING OUTCOMES

Concept of structural reliability and safety with application to marine loads and structures. Procedures for reliability assessments. Capacity of interpreting structural reliability assessments and of performing short/long term predictions of sea loads.

AIMS AND LEARNING OUTCOMES

The course aims at providing the student with probabilistic methods for the design of marine structures

PREREQUISITES

Undergraduate courses on ship structures design, module on Statistics and Probability

TEACHING METHODS

Theoretical lessons and class exercises for a total of about 60 hours

SYLLABUS/CONTENT

The general concepts of algebra of sets, events and their relationship, probability and conditional probability, provided by the preceding course of Statistics and Probability are applied to structural design cases.

Stochastic variables and vectors, joint probability distributions and inherent indexes - stochastic processes and inherent properties.

Stochastic models for loads and resistances and inherent uncertainties with reference to ship structures. Short and long term predictions of sea loads

The concept of reliability of systems and of structural reliability - reliability evaluation methods.
