Learning objectives
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.
Prerequisites
It is suggested to have attended the courses of Advanced Structural Analysis and Numerical Methods for Structural Analysis.
It is useful to have knowledge of MatLab software and familiarity with commercial software based on finite element method.
Course unit content
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.

Teaching methods
Theory supported by exercises.
Assessment methods and criteria
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.
Other information
It is strongly recommended to attend lessons.
