Presentazione
The course is intended to provide principles and practices involved in approaching current problems in earthquake engineering. After an introduction to the subject of dynamical systems, the course will present modern solutions to questions concerned with the seismic response of structures, as well as seismic design. Exercise lessons, consisting of both numerical and design applications, aim at introducing students to handling efficient structural dynamics tools, so helping them to competently use international standards and rules for earthquake resistant structures.
