After visiting the lecture the students can understand the relevant wave propagation phenomena in the soil and get an overview over field methods. They get the competence to analyze serviceability problems of structures placed on the ground. After the introduction in the phenomenology of earthquakes, where the students get an overview for understanding the phenomena, the impact of wave propagation and soil characteristics, they get an overview over the stability of dampers under earthquakes.
In the lecture aspects in wave propagation in the soil are described starting with the wave propagation in the elastic media. The wave phenomena are described on a continuum mechanical approach based on the Lamé equations. The relevant waves in the soil are illustrated. The focus is given on an un-layered and a layered soil. Also the impact of water and porosity is illustrated. Thematic outline: - Wave propagation phenomena - Dynamic parameters of the soil - Modeling aspects - Serviceability - Technical seismic engineering
