Educational objectives
Knowledge of the Monte Carlo simulation for random variables and vectors, stochastic processes and fields. Knowledge of problems connected to implementation of numerical codes for solving random problems in structural engineering.
Prerequisites
In order to be able to understand and apply the majority of the techniques described within the Course, the following knowledge is recommended:
Maths: derivation and integration techniques for one-dimensional and bi-dimensional functions; differential equations.
Physics and Meccanica Razionale: vector calculus; equilibrium equation both for static and dynamic problems.
Structural Mechanics and Strength of Materials: equilibrium, compatibility and constitutive equations for the elastic continuum; beam elastic deflection equations.
Non-linear mechanics and structural dynamics: plane problems (plane stress and plane strain problems); equilibrium equation for discrete systems (multi degree fo freedom - MDOF); modal analysis and modal superposition technique.
Solution of structural systems using the Finite Element Method (FEM).
Teaching methods
Face-to-face both theoretical and practical classes.
Other information
Attendance to classes: optional but strongly advised.
Learning verification modality
