The PhD in Structural and Geotechnical Engineering includes the themes of the disciplinary scientific fields of Structural Mechanics, Structural Mechanics and Geotechnical Engineering that can be found in the following declaratory: STRUCTURAL MECHANICS The interest is in the scientific activity and teaching and training concerning the solid mechanics, materials and structures. The scientific-disciplinary issues such as the experimental and theoretical knowledge are on how to solve problems related to the determination of the mechanical behavior of structures, bodies or resistant elements of civil engineering, architecture, other engineering sectors as other applied sciences. The problems faced involving aspects relating to statics, dynamics, stability, fracture mechanics, calculation at strength and experimental mechanics as a verification of the models. The techniques and methods used are typical of physical and mathematical modeling, computational mechanics, experimental mechanics, diagnostics and structural identification. Other issues concern the interaction between the structures and the physical environment that surrounds them, the mechanics of innovative and unconventional materials structures, regardless of the scale of their observation and modeling, the critical study of the historical development of the models used and reading structural key historical and monumental artifacts. STRUCTURAL ANALYSIS AND DESIGN The interest is in the scientific and educational training relating theories and techniques directed to both the structural design and the design of new buildings and the verification and the structural rehabilitation of existing ones. The scientific subject contents are: actions on structures, including seismic activity, the behavior of the structures depending on the type and morphology, materials, techniques and technologies, the interaction with the ground and with the 'environment, and the ways of use and control strategies; methods and tools for structural design, construction and operation of facilities; vulnerability assessments, reliability, comfort, safety and durability; experimentation, testing and monitoring of buildings; historical investigations on the building, security checks and structural intervention solutions applicable to construction and historical monuments; structural architecture. GEOTECHNICAL ENGINEERING The interest is in the scientific and educational training related to principles, theories and analytical, computational and experimental methods for the physical-mechanical modeling of soils and rocks, including the evaluation of their behavior in boundary value problems where those natural materials interact with typical civil engineering structures, under static and dynamic conditions. In particular, part of the research activity focuses on the experimental observation of the mechanical behavior of soils and rocks at the element level and on the related attempt to formulate non-linear constitutive relations to model their essential features. Those mathematical models, once properly formulated, often require the development of specific numerical integration schemes for their implementation into numerical codes: this activity leads to further research activities that characterize the geotechnical sector. The numerical analysis of boundary value problems allows further research to be carried out with reference to specific geotechnical structures including foundations, underground constructions, excavations and retaining structures, tunnels, embankments or earth dams, all requiring a detailed geotechnical characterization to be carried out aiming at defining an ideal geotechnical model of the involved soil or rock deposits. This latter activity too can itself be approached in an academic prospective, as being central in the solution of any geotechnical problem. The outcomes of the applied research discussed above can have a direct impact on the design and construction techniques to be adopted in real civil engineering projects. Last, but not least in terms of relevance, is the geotechnical research contribution to the environmental risk assessment and mitigation, which involves at different scales many aspects of the world around us. This includes the analysis of the stability of natural slopes, the seismic-related site response analysis and that of the occurrence of liquefaction phenomena, together with the man-induced environmental damages, like those related to polluted industrial sites. As one can see, the themes of the PhD in Structural and Geotechnical Engineering are central in Civil Engineering and Architecture sector, but may also have wider variations to other sectors such as Industrial Engineering (mechanical, aerospace, naval) remaining characterized, discounted the importance of the theoretical approach, with a strong focus on implementation issues. Notwithstanding this strong connotation, there is also space for different research topics as security in the event of extreme actions such as fire and explosions, unconventional mechanical problems, frontier technologies based on coupled behaviors or with biological inspiration, the bio structural issues, heuristic optimization, security problems, energy harvesting, resilience, sustainability, forensic engineering, aspects of the history of structural mechanics and design methods. The PhD course is organized into two curricula: c) a) Structural Engineering d) b) Geotechnical Engineering but all theses that consider cross-cutting themes are certainly encouraged. The PhD Course in Structural and Geotechnical Engineering considers as essential to have an appropriate cross-culture, to support students in both academic careers/research and toward professional paths/high level consultancy.
