THEORY AND DESIGN OF STRUCTURES IN R.C. AND IN P.R.C. B
Learning outcomes of the course unit
The course extends the knowledge of reinforced concrete (CA) structures to prestressed concrete structures (CAP). The topics of the course permit to design a simple prestressed concrete structure according to Eurocode 2:2005.
Teoria e Progetto di Strutture in C.A. e C.A.P. - A- (Theory and design of reinforced and prestressed concrete structures - A)
Tecnica delle Costruzioni (Structural mechanics)
Course contents summary
Stability: nonlinear behavior of a RC slender column fixed at the base, analysis of an isolated column according to Eurocode 2, stability of RC frames, analysis of a RC frame by means of P-Delta method and nonlinear finite element analysis.
Prestress: pre-tensioned and post-tensioned beams, forces equivalent to prestress, analysis of statically indeterminate prestressed beams
Prestress losses: friction between wire and duct, shrinkage, creep, relaxation of prestressing steel
Creep and shrinkage: drying and autogenous shrinkage, creep function, EM, AAEM, behavior of a cross section subjected to creep and shrinkage by means of AAEM, behavior of a continuous beam subjected to forces or settlements by means of AAEM
Design of disturbed regions: strut and tie method, corbels, deep beams, supports, Anchorage zones.
Slabs: design of a RC slab and reinforcement details
Structural Analysis: Linear elastic, plastic analysis, nonlinear analysis, pshover analysis.
