Learning outcomes |
The curricular unit aims to develop knowledge in terms of structural strengthening, creating the following competences: a) Evaluation of the resistant capacity of existing structures; b) Understanding the process of loading transference between element build at different ages; c) Understanding the mechanics of different strengthening techniques; d) Perception of the seismic strengthening problem; e) Identification and understanding of specific aspects of old buildings and justification of the strengthening strategies; f) Understanding of the execution techniques.

Syllabus |
1) Structural strengthening techniques: a) Strengthening of structural elements by concrete jacketing: Description of the technique; Models of equilibrium; Behaviour of the interface; Design and execution. b) Strengthening of structural elements by external reinforcement: Description of the technique; Models of equilibrium; Connection between the reinforcement and strengthened element; Design and execution. 2) Seismic strengthening of buildings: Framing and analysis of the problem; Framing in the relevant codes; Strategies and techniques of strengthening. 3) Strengthening of old buildings: Analysis of specific characteristics and their influence on the structural behaviour; Strategies and techniques of strengthening; Analysis of equilibrium models; Methodologies of structural analysis.

Teaching Methodologies and Assessment Criteria |
The syllabus is presented with analysis and discussion of current scientific and technical publications that demonstrate the viability of strengthening techniques, limitations, mechanical behavior and execution aspects. Another component, theoretical-practical, corresponds to the analysis of specific problems of structural strengthening, framed in a design process. Additionally, are presented and analyzed examples of strengthening solutions. The evaluation methodology implies written and oral tests. The written tests globally evaluate the acquired knowledge in the teaching components. The oral tests are based on the work developed in the theoretical-practical component. Additionally, the goal is to evaluate the work developed autonomously.
