Base Knowledge
Reinforced Concrete and Structures
Teaching Methodologies
Theoretical-practical exposition classes; problem solving with a practical approach and technological understanding; discussion of ideas and solutions; written and oral presentation and discussion of works and reports.
During the presentation of theoretical and practical subjects, students will be motivated to participate actively in class, and will be strongly encouraged to develop autonomous work. In classes, students will also be encouraged to technically and scientifically interpret practical problems. The clarification of doubts both in solving exercises and in the interpretation of theoretical subjects will be an important complement in the students’ learning process, with a special focus on case studies. This process will be complemented by research and autonomous development of practical work, based on the syllabus.
Learning Results
Learn the theory and practice on the durability and strengthening of reinforced concrete structures.
Application of knowledge; increased understanding of topics associated with concrete constructions; judgments and decisions making; increased ability to communicate and to discuss technological matters; Development of critical sense and self-learning.
Acquire new knowledge and understanding issues related to durability and to rehabilitation and strengthening of concrete structures; learn the fundamentals of degradation mechanisms and of protective measures to eliminate or mitigate this risk; learn to assess the state of concrete structures; learn how to various rehabilitation techniques and learn the basic calculation of structural strengthening; provide students with skills to identify causes, make judgments and develop and monitor the execution of solutions in the area of rehabilitation and strengthening of concrete structures.
Program
1 – Durability of structures
Degradation of concrete structures: causes and mechanisms
Structural protection measures to reduce the deterioration risk; standard rules regarding durability and restoration (EN 206 and EN 1992, EN 1504)
Estimated service life and applicable standards (LNEC E464 and E465)
High durability eco-efficient concrete
Reinforcement or replacement of reinforcing bars
Crack treatment and sealing
2 – Strengthening of concrete structures
Causes of reinforcement need
Seismic vulnerability
Main strengthening techniques; advantages and disadvantages Shoring and load transfer in strengthening interventions
3 – Design and detail of structural strengthening solutions
Reinforcement by increasing the cross-section (RC jacketing)
Reinforcement by adding elements (steel plates and profiles, gluing FRP’s)
Reinforcement by applying external prestressing (steel cords; FRP laminates – adherent/non-adherent)
