MECHRES20 - Mechanics and Performance of Resilient Structures and Infrastructures
Registration deadline: 5 September 2020
Topic and Objective
The tremendous impact of natural hazards, such as earthquakes, tsunamis, flooding, etc, which triggered technological accidents, referred to as natural-technological (NaTech) events, was demonstrated by:
i) the recent Tohoku earthquake and the following Fukushima disaster in 2011;
ii) the UK’s 2015 winter floods which topped £5bn, with thousands of families and businesses that faced financial problems because of inadequate or non-existent insurance.
Therefore, today there is a stronger need than ever to grow researchers that combine a robust academic foundation in linear/non-linear dynamics, control, knowledge of hazard and risk with practical experiences, technological expertise and conviction to furthering research with an entrepreneurial spirit.
Hence, the objective of the Summer School is to offer innovative training ground, experience in risk-based simulation/development of structures, vibration reduction, control and disaster resilience subjected to earthquakes, wind, etc as well as laboratory experience.

Introduction to Performance-Based Engineering and Resilience (PBE&R) against wind hazards (L. Caracoglia)
The scope of this section is to introduce the student to the latest developments in the field of performance-based engineering and resilience against wind hazards. The section will start with a brief examination of wind fields, turbulence and aerodynamic loads for structural engineering design. Analysis methods for the estimation of the structural response under random wind loads and the evaluation of flow-induced vibrations will be presented. Applications of probability principles will be examined in relation to the design of long-span bridges and tall buildings, by incorporating principles of risk analysis, life-cycle assessment and resilience. Finally, a tutorial with examples and practical applications will be discussed.
Passive, semi-active and active control. Structural dynamics in the state-space. Passive system design: passive increment, passive coupling, passive isolation. Active and semi-active enhancement. Model-driven and data-driven design. Applications. Active control of cable oscillations. Nonlinear viscous coupling for seismic retrofitting.
- Flexural band gaps in periodic piping systems (F. Aloschi)
- Design of passive and semiactive control systems (F. Potenza)
- Seismic risk evaluation of critical equipment for major-hazard industrial plants (D. Corritore)
- Performance-Based Engineering and Resilience against Wind Hazards (L. Caracoglia)
The registration fee (€ 100) will cover complete course materials, including slides and hands-on tutorials. It is worth 4 credits with homework assignments. Registration is required.
