35450 - STRUCTURAL SAFETY

Conoscenze e abilità da conseguire

The method for safety evaluation and risk assessment of civil structures will be studied. Definition of loadings and structural safety will be given in a probabilistic framework. Risk assessment of civil structures in earthquake regions will be analyzed with details.

Contenuti

The student will be acquainted with the different methods available at the time for evaluation of the safety and risk associated with civil structures.The objective of these methods being the evaluation of the probability of violation of a limit state function (such as collapse). The failure probability will be obtained from the various sources of uncertainty/randomness associated with: loadings, material properties, structural geometry, boundary conditions, as well as structural models and analysis techniques. The course will also cover example of structurally sound systems as well of major structural collapse/failures both with reference to static and seismic loadings. The reasons behind the selection of the safety factors used in common Codes will also be covered.
