PHD COURSE IN STRUCTURAL AND GEOTECHNICAL ENGINEERING DOTTORATO DI RICERCA IN INGEGNERIA STRUTTURALE E GEOTECNICA

Department of Structural and Geotechnical Engineering Dipartimento di Ingegneria Strutturale e Geotecnica

TITLE:

DESIGN OF WIND-EXCITED CIVIL STRUCTURES: PHENOMENOLOGICAL BASIS, PERFORMANCES ASSESSMENT, SOLUTIONS AND CASE STUDIES

ABSTRACT: What does the proper design of wind-excited civil structures need? What is the research practice in Wind Engineering today? How can we imagine tomorrow solutions for today open issues? The PhD course aims at providing some partial responses to the questions above, by lectures, seminars and brainstorming. Teaching lectures on established research and practice. The design of wind-excited Civil Structures needs, among others, sound phenomenological background in aerodynamics and aeroelasticity to set the problem, conceptual design abilities to solve the problem, analysis tools to assess the performance of candidate solutions. Teaching lectures select well-established fundamentals in Wind Engineering about the above issues. Seminars on current research. Additional seminars are focused on recent advances on selected topics in Wind Engineering. A view of research methods, as well as goals and achievements of selected research projects in the field. Brainstorming on research frontiers. As a closing loop step, brainstorming sessions are intended to seed some doubts and shed some light on open issues in Wind Engineering. Open minded, informal discussions towards potential step changes with respect to the current state of practice and knowledge. TARGET AUDIENCE: PhD students (main), Post-doctoral fellows (secondary), Researchers, Engineers LAYOUT OF THE COURSE:

• 3 days (8+8+4 hours), 20 hours in total • First two days: 6 hours of teaching lectures on established research and practice + 1 hours of

seminars on current research + 1 hour of brainstorming on research frontiers • Third day: 4 hours of lectures on established research and practice

DATES: Thu 14th, Fri 15th and Sat 16th September 2017, following X EURODYN 2017 (10th - 13th September). ORGANIZERS: Luca Bruno (Politecnico di Torino), Francesco Petrini (Sapienza Università di Roma)
