The course focuses on the safety assessment of existing buildings and the criteria for designing the strengthening interventions of various structural types, in particular masonry and reinforced concrete. The structural rehabilitation is faced, firstly, by considering the interventions techniques applicable at scale of the structural elements and, then, by analysing their repercussions at scale of the global behaviour, with the aim of outlining the strategies more effective in terms of strength, stiffness and ductility varying the features of the structure under examination. Particular attention is paid to the effects/design of interventions related to the seismic behaviour. Moreover, some specific analytical models for the seismic assessment of monumental buildings (in particular, palaces, churches and towers) are illustrated that are very useful for aims of mitigation policies at large scale.
Theoretical lessons (45) + Exercise (15)
The exercise comprise the use of software specifically addressed to the analysis of masonry buildings.
The course aims to provide to students the tools/expertise necessary to design the rehabilitation interventions on existing buildings (masonry and reinforced concrete structures), with particular reference to the seismic assessment. Moreover, some analytical models specifically addressed to the assessment of monumental buildings, that constitute an inestimable value of the Italian and European countries, are illustrated: such tools are those currently adopted by the MIBACT ministry with the aim of providing to students tools also useful to act with administrative offices.
Safety assessment of existing buildings, with particular reference to the seismic action: differences in the methodological path between new and existing buildings; as built information; use of sensitivity analysis for addressing the plan of investigations.
Masonry buildings (such contents are complementary to those treated in the “Structural Rehabilitation 1” course): seismic response (global response mainly associated to the in-plane response of walls; local mechanisms mainly associated to the out-of-plane response of walls); design of interventions focusing the attention on the repercussions of different solutions at global scale; exercises focused to learning some software specifically oriented to the nonlinear analysis of masonry buildings and to quantitatively assess the effectiveness of different intervention strategies.
Reinforced concrete buildings: interventions techniques based on traditional and more innovative approaches to be applied at scale of single structural elements and analysis of their repercussions at global scale.
Monumental masonry buildings: analytical models for the seismic assessment and plan of mitigation policies of churches, palaces and towers. Exercises focused to apply such analytical models on some real buildings.
