Educational Goals

Learning the basic concepts of dynamic loading and the response of linear structures to such loads. Learning the basic concepts of engineering seismology.

Content

Linear vibration of structures. Elements of engineering seismology.

Extended Syllabus

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.

Elements of Engineering Seismology - Elements of seismic wave propagation theory, seismic instrumentation, seismic hazard concepts.
