Code	14586
Year	1
Semester	S2
ECTS Credits	6
Workload	PL(30H)/T(45H)
Scientific area	Mechanics and Structures
Entry requirements	Good base knowledge on “Strength of Materials”, “Structural Analysis” and “Structural Concrete”
Learning outcomes	The pedagogical objectives of the course are defined in terms of skills to be acquired by students, prioritized into three levels, in order of decreasing depth and relative semester workload: Proficiency of a) Design of statically determinate and indeterminate prestressed concrete structures; b) Supervision of the construction of elements and structures of prestressed concrete. Understanding of: a) Fundamental principles of prestressed concrete; b) Materials, methods and techniques for prestressing and complementary operations. Recognition of: a) Special requirements for the demolition of prestressed concrete structures; b) Rehabilitation solutions for prestressed concrete structures.
Syllabus	THEORETICAL CLASSES 1. Introduction. Prestressing methods and techniques. 2. Fundamental concepts. Comparisons between prestressed and reinforced concrete. Material properties. Section analysis. 3. Prestress losses. Instant losses and deferred losses. 4. Design of statically determinate prestressed concrete beams. Service limit states. Limit stress equations. Magnel diagram. Limit zone. 5. Stability check. Ultimate limit states of resistance in bending and shear. 6. Anchorage zones. Action of localized forces. Safety check and construction provisions. 7. Statically indeterminate structures. Primary and secondary bending moments. Linear transformation and concordance. Equivalent loads method. Service behavior and ultimate resistance. Redistribution of internal forces. PRACTICAL CLASSES Solving practical problems on the subjects exposed in the theoretical classes.
