Objectives

Sensibilization of the pupils for the problems, each time more frequent, related with deterioration, the whitewashing and the reinforcement of structures, namely the concrete structures. Relevance is given to the processes of characterization of the state of the structures, to the techniques of repairing and structural reinforcement, to the corresponding taxable incomes and the specific particularitities of this type of projects.

Program

Introduction: on general aspects to deterioration, conservation, whitewashing and reinforcement of structures. Deterioration: aggressive actions; processes of deterioration of concrete, the armors and other structural elements; effect and prevention of deterioration; consigned relative aspects to the structural durability in Eurocode 2. Evaluation of the state of structures: inspections; evaluation processes "in situ" of the conditions of the structures; non destructive testings and laboratorials assays; instrumentation and comment of structures; analysis and interpretation of the structural behavior. Techniques of repairing and structural reinforcement: treatment and reconstitution of concrete; treatment of fissures; whitewashing and reinforcement of structural elements by means of armors you add, metallic elements you add, concrete “encamisamento”, molded or projected; reinforcements by means of composites materials. Sizing of structural reinforcements: reinforcement of beams and flagstone for metallic plates and armors you add, with or without encamisamento, and for composites materials; reinforcement of pillars. Whitewashing and reinforcement of structures and its foundations: general aspects; type and examples of interventions.
