SOIL MECHANICS AND DYNAMICSAcademic Year 2021/2022 - 2° Year
Credit Value: 6
Scientific field: ICAR/07 - Geotechnics
Taught classes: 28 hours
Exercise: 30 hours
Term / Semester: 1°
The course aims to provide advanced knowledge on the static and dynamic behaviour of soils, necessary for using the main design software. The main constitutive models implemented and implementable in FEM, FDM, etc., softwares, are illustrated. Advanced static and dynamic laboratory tests are discussed. The following other topics are dealt with: propagation of waves in the subsoil, modification of the seismic signal from the rocky base to the surface of the ground; modification of the seismic signal due to the foundation-soil kinematic interaction; influence of the deformability and dissipative capacity of the foundation-soil system on the inertial response of the structure; dynamic liquefaction phenomenon.
Frontal lessons through PowerPoint presentations. Seminars in collaboration with geotechnical companies and/or engineers, teachers from other national and international universities. Exercises in the classroom.
A technical visit to a construction site in Sicily is planned to increase the student's knowledge of the topics discussed in the classroom and bring the student closer to the world of work and practice.
Suppose the teaching is given in a mixed or remote way. In that case, the necessary changes may be introduced to the previously stated program envisaged and reported in the syllabus.
