bridges and other strategic infrastructures condition the life and economic development of modern society. Management and maintenance of these structures have assumed increasing importance with the increase in their complexity and age. In this context, the structural health monitoring (SHM), the management of the information acquired and their correct interpretation have a central role in maintaining a high quality of the public service , ensuring safety and planning interventions.
The course will give the main concepts for the management of the life cycle of infrastructures (with reference to both transport infrastructures and those for safety, health and education). It covers the main maintenance techniques, inspection methods, monitoring techniques and the basic principles of the economic foundations (cost/benefit analysis) and multilevel approaches for prioritizing the planning of actions aimed at the infrastructure management.
A framework of the main problems relating to the management and maintenance of infrastructures will be given, with the aim of providing the basic knowledge necessary to define the maintenance, inspection and monitoring programme. The description of real case studies will allow the themes illustrated during the course to be detailed to existing infrastructures. At the end of the course, students should have skills in the planning and management of activities for defining the state of infrastructures and managing their correct maintenance; to plan and manage an infrastructure monitoring campaign, also knowing how to evaluate the different choices, to evaluate the convenience of an intervention based on a cost-benefit analysis
Students of the course must possess the basic concepts of structural engineering and structural dynamics
Lessons are provided in frontal teaching mode, providing lecture notes on aulaweb. Some in-depth seminars are also planned.
Working students and students with learning disability certification, other disabilities or special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and exam methods which, in compliance with the teaching objectives, take into account individual learning methods

Oral test in which an in-depth study on a specific topic chosen by the student will also be discussed
At least two questions will be asked on the topics covered during the course which will be aimed at ascertaining the student's ability to plan and manage activities relevant to the state of infrastructures, the ability to design and manage structural monitoring, critically evaluating the different solutions, the ability to evaluate the costs and benefits of different intervention choices and operational decisions
