Dimensioning of p.r.c sections, designing of the p.r.c. sections for full or limited prestressing level, the cables positioning, Resultant cable, Guyon fuse, equivalent load system, calculus of the hyperstatic reactions due to prestressing, c-line determination, Guyon theorem and concordant cable, anchorage of the prestressing forces, local details.
STEEL STRUCTURES: Modeling, design and checks of the structural elements of steel buildings. Bolted and welded connections. Compesed elements. Flexural and Flexural-Torsional Instability problems.
DEISGN OF D-REGIONS: Introduction to the modeling of D-Regions. Empirical methods based on photo elasticity and analytical models. Construction of Strut & Tie models. Depth beams and corbels. The diffusion of the prestressing forces
STEEL-CONCRETE COMPOSITE STRUCTURES: the beams, technology, typical composite structures, statics of the sections in elastic and ultimate conditions, constructive phases, the influence of the supports. BEHAVIOUR OF THE FRAME STRUCTURES: the behavior under vertical and horizontal loads, shear type frames, deformable beams frames, the ductility concept, local and global ductility.
