Year	2
Semester	S1
ECTS Credits	6
Workload	PL(30H)/TP(30H)
Scientific area	Mechanics and Structures
Entry requirements	-
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.
