The aim of this course is to present the fundamental tools for evaluating the response of a structure submitted to dynamic loads and to provide the scientific and technical knowledge for the design of structures for earthquake resistance.

Dynamics of structures
Single-degree-of-freedom systems. Free-vibration response (undamped and damped vibrations). Response to harmonic, periodic, impulsive and general dynamic loading. Elastic-plastic systems.
Multi-degree-of-freedom systems. Free vibrations (natural frequencies and modes), principal coordinates. Damping. Uncoupled equations of motion. Mode-superposition procedure. Methods for the step-by-step integration of the equations of motion. Non-linear systems.
Distrubuted-parameter systems. Free vibrations of beams under bending. Free vibrations of plates.
Discretization methods. Rayleigh-Ritz, finite elements.
Dynamics of frames.

10 Structural modelling for finite element analysis of structures.

Modalità d'esame
The students have to design a building made of reinforced concrete, steel or masonry. The examination consists into the design discussion and into an oral examination where the knowledge of the course topics will be checked.
