- Elastic displacement response spectrum
- Determination of the target displacement for nonlinear static (pushover)
- Earthquake hazard in Austria
- EMS-98 intensity scale - in short
- Dynamic soil properties (strength parameters, rigidity and damping parameters)
- Requirements for the site and the soil (choice of site: stability of embankments, potentially liquefiable soils, excessive settlement of soils under cyclical loading, subsoil exploration and subsoil investigation: determination of the subsoil class to define the earthquake effects, dependency of the soil stiffness and damping on the displacement magnitude)
- Dynamic design of foundations (general requirements, rules for the conceptual design, design values of the actions, proof and design criteria)
- Soil-structure interaction
- Dynamic design of retaining structures (general requirements, choice of the type of structure and general design considerations, calculation methods: general methods, simplified methods: pseudo-static calculation, stability and strength proofs)
- Previous knowledge expected
-
Knowledge in Geotechnical Engineering and in Applied Geotechnical Engineering
- Objective (expected results of study and acquired competences)

With this course, the students will understand the structure and soil as a static unit in which the dynamic actions of the earthquake load (soil dynamics) play a pivotal role. They will understand the interplay between structure and subsoil.
After this course, the students will be able to understand the dynamic actions of the soil and their local (topographical) effects and calculate them in accordance with the standards. Therefore, they will be able to carry out the design of geotechnical structures due to earthquake loads.
