Abstract

Part 1: Theory and application of structural dynamics for single and multiple degree-of-freedom systems subjected to harmonic, periodic, short and seismic excitation. Part 2: Theory and guidelines for practical solutions to vibration problems of lively structures (pedestrian bridges, floors, etc.) induced by people, machinery or wind. Laboratory demonstration of a tuned mass damper.

Objective

Main objectives of the lecture are: 1) Acquirement of the theoretical background relevant to linear structural dynamics. 2) Development of a “feeling for dynamics problems”. 3) Identification of common dynamics problems in structural engineering and of the relevant solutions.

Content

1) Single-degree-of-freedom systems: Modeling, equations of motion, free vibrations with and without damping, harmonic, periodic and short excitations, Fourier series, impacts, time history analysis, response spectra. 2) Multi-degree-of-freedom systems: Modeling, equations of motion, free vibrations, modal analysis, damping, response spectrum method, Rayleigh’s quotient 3) Vibration of lively structures induced by people, machinery and wind: Problem description, dynamic action, effects, tolerable values, design rules (tuning method, amplitude limitation)
