Introduction - Actions causing structural vibrations. Discretization of mass-distributed systems by the Lumped Mass approach and by the Assumed-Modes method.
Single Degree of Freedom Systems (SDOF) - Undamped oscillator: free vibration, harmonic response. Damped oscillator: free vibration, harmonic response, response to a periodic force.
Impulse response function. Arbitrary forcing function: convolution. Support motion. Experimental techniques to measure the viscous damping ratio. Linear hysteretic damping.
Multi Degrees of Freedom Systems (MDOF) - Equations of motion for undamped and damped systems (linear viscous damping). Rotating umbalanced masses. Undamped systems: free vibration, natural frequencies, modal vectors and their properties. Response to harmonic, periodic and arbitrary forcing functions by the modal superposition method. Proportionally damped systems: response to harmonic, periodic and arbitrary forcing functions by the modal superposition method.
Elastic Response Spectrum - Definition. Response spectrum analysis.
Frequency Domain Analysis - Response of SDOF and proportionally damped MDOF systems to a transient forcing function via frequency domain analysis.
