Geotechnical earthquake engineering/Structural earthquake engineering

GEOTECHNICAL EARTHQUAKE ENGINEERING The dynamic response of the subsoil has a strong influence on seismic risk. Indeed it affects the seismic hazard and the soil-foundation-structure interaction. The course, after the introduction of the basics of seismology and soil dynamics, deals with geotechnical issues of engineering structures under seismic loads. STRUCTURAL EARTHQUAKE ENGINEERING The course is intended to provide principles and practices involved in approaching current problems in earthquake engineering. After an introduction to the subject of dynamical systems, the course will present modern solutions to questions concerned with the seismic response of structures, as well as seismic design. Exercise lessons, consisting of both numerical and design applications, aim at introducing students to handling efficient structural dynamics tools, so helping them to competently use international standards and rules for earthquake resistant structures.

GEOTECHNICAL EARTHQUAKE ENGINEERING Practical examples will be presented in the classroom to make the students familiar with the topics of the course. Some practical examples will be devoted to the use of computer softwares for the numerical simulation of geotechnical earthquake engineering problems. STRUCTURAL EARTHQUAKE ENGINEERING Both numerical and design applications will be developed (18 h). The classroom exercises are dedicated to numerical applications aimed at analyzing the dynamic and seismic response of simple structures. The classroom design activities include assistance activities during which the necessary information will be provided to develop a complete project, with calculation reports and graphical drawings, of the structure of a building located in an earthquake zone. The design work is developed starting from architectural drawings.

GEOTECHNICAL EARTHQUAKE ENGINEERING Exam: Compulsory oral exam; Individual essay STRUCTURAL EARTHQUAKE ENGINEERING Exam: Compulsory oral exam; Individual project GEOTECHNICAL EARTHQUAKE ENGINEERING The exam is composed by an homework in 3 parts and an oral exam. The homework is intended to provide the practical skills necessary for the quantitative assessment of seismic hazard at a site, including the evaluation of the stability of a retaining structure, which will consider also the evaluation of its performances. The oral exam is intended to evaluate the comprehension of the background theory and to assess the full understanding of the topics covered by the homework. Frading will be based in equal parts on these assessments STRUCTURAL EARTHQUAKE ENGINEERING To be eligible for the exam, students must have satisfactorily completed the structural design of a building developed during the course. The final exam is oral and is aimed at evaluating all learning outcomes also on the basis of a discussion of the project. The discussion of the project weighs up to one third of the total score, however an insufficient grade on this part will automatically result in the examination being rejected
