Learning outcomes |
The curricular unit aims to develop knowledge in terms of structural strengthening and rehabilitation, 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.

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 (70%) globally evaluate the
acquired knowledge in the teaching components. The oral tests (30%) are based on the work developed in the
theoretical-practical component. Additionally, the goal is to evaluate the work developed autonomously.
