The course consists of three parts.
1) Introduction to signal analysis. Autocorrelation and crosscorrelation. Analysis in the frequency domain, Fourier transform and power spectra. Wavelet theory and applications. Transfer functions.
2) Ground motion time histories, analysis, correction and filtering. Intensity measures, energy and pulse-like content. Signal rotation for the extraction of mean values and directivity azimuth. Synthetic and semisynthetic accelerograms.
3) Characteristics of structural dynamic response time histories. Elastic and inelastic response of single degree of freedom systems. Deterministic methods for the evaluation of structural dynamic characteristics and their transformation. Application of wavelets. Design based evaluation. Probabilistic methods based on fragility curves.
Homework problems including a small project based on the analysis of structural response time histories under severe ground motion are used to cover all topics.
