Objectives
The course provides the theoretical principles and the methodologies for the design of structures under earthquakes loads. The course consists of two parts. The first one describes the principles of dynamics of solids and structures for understanding the behaviour of systems under dynamic loads. The second part illustrates the principles of earthquake engineering also with reference to the more recent Italian and European codes. The course includes lectures and laboratory. Laboratory includes problem-solving sessions on one and multi degree of freedom systems and the analysis of a building under seismic load.
