Durabilidade e Reabilitação de Estruturas

Strength of Materials; Construction Materials.

Theoretical-practical lessons of exposition, resolution of exercises, discussion (debate and sharing ideas), oral and written report presentation. During the presentation of theoretical and practical subjects students will be surveyed to maintain an active participation in the class. In class, the students will be encouraged to interpret scientific-technical practical problems. Sessions to clarify doubts either in resolution of exercises or in the interpretation of theoretical topics will be an important complement during the learning process of the students.

Goals:

Learn the theory and the practice related with the durability and rehabilitation of structures.

Generic skills:

Apply the theoretical knowledge; increase the understanding about the topics related with urban space; make judgments and decisions; increase the capacity to communicate and discuss technologic issues; develop the ability to criticize and self-learning.

Specific skills:

Acquire knowledge and understanding capacity in the field of durability and rehabilitation of structures, learn the fundamental principles about the deterioration mechanisms and the protective measures to eliminate or reduce this risk; learn to evaluate the actual state of the structures; learn the several techniques of rehabilitation and structural strengthening; provide students with new skills to identify causes, make judgments, develop solutions and supervise the execution of tasks in the field of rehabilitation of structures. 

1. Concepts and principles about structural degradation in concrete, wood-bases or steel

Main types of structural materials and respective parameters.

Basic concepts about the durability of structures.

Causes and deterioration mechanisms: physical, chemical and biological processes.

Steel reinforcement corrosion in structural concrete. Exposure conditions.

Protective measures of structures to reduce the risk of deterioration, standard rules related with the durability os structural concrete, wooden structural materials and steel.

2. Evaluation and rehabilitation

Evaluation the actual state of structures: identify anomalies/ pathologies and characterize the state of deterioration of structures.

Technical inspections and testing.

Principles and techniques of repairing and structural strengthening of concrete structures: sealing cracks; shotcrete; new layers of reinforced concrete; bonding steel plates; bonding polymeric composites.

Principles and techniques of repairing and structural strengthening of wooden or steel structures.

3. Materials and innovative techniques of strengthening

Characterization of new structural materials used in rehabilitation.

Bond between the existing structural materials and the new materials. Behavior of composites.

Examples of rehabilitation of structures.

Written exam (8 points) to be carried out during the period of exams. Research works with presentation and discussion (12 points). Those works can be done individually or in group (maximum 2 students) and must be submitted with the format specified by the teacher; the works will be evaluated only for the students that accomplish with minimum of 70% of presence in classes. The approval requires the achievement of at least 9.5 in the final result and a minimum of half in each component.

The regulations in force at the IPC shall be applied to all cases of attempted or completed academic fraud. Whenever there are doubts as to whether academic fraud has occurred, the professor reserves the right to invite students to provide clarifications in the form of an oral examination.
