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.

Modalità di esame: Prova orale obbligatoria; Progetto individuale;
Exam: Compulsory oral exam; Individual project;
To be eligible to take the exam, students must have satisfactorily completed the term papers and project assigned during the course. The final examination is oral and is intended to assess all learning outcomes also based on a discussion of the project. The discussion of the project weighs up to one third of the total score, however an insufficient grade on this part will automatically result in failing the exam.
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
