Objectives

General aspects, mechanical models, structural analysis and verification of existing masonry buildings. Damage analysis, investigation and diagnosis techniques, and intervention strategies on structural masonry and timber members, as well as on complete buildings, also of historical and artistic value. Damage analysis, investigation and diagnosis techniques, seismic evaluation procedures and intervention strategies on R/C structural members. Advanced seismic retrofit technologies for building structures. Development of a design exercise by each student, under the direction of the teaching staff.

Acquired skills

- Ability to perform structural and diagnostic assessment analyses of masonry, timber and R/C structural members.
- Ability to conceive and design rehabilitation and seismic improvement interventions of masonry , timber and R/C structural members.
- Ability to conceive and design seismic retrofit interventions of masonry and R/C buildings, also based on advanced protection technologies.
