Programma sintetico del corso:
THEORETICAL LECTURES
- types of bridges;
- isotropic and orthotropic plates;
- discretization methods;
- profilati sottili;
- actions on bridges;
- analysis of local effects;
- girder bridges;
- box-girder bridges;
- mechanics of ropes;
- suspended bridges;
- cable-stayed bridges.
LECTURES ON NUMERICAL ASPECTS
Use of Finite-Element codes and semi-analytical methods to:
- build up the influence lines;
- to solve isotropic and orthotropic plates;
- analyze local effects;
- analyze the behavior of girder bridges;
- analyze the behavior of box-girder bridges.
LECTURES ON DESIGN ASPECTS (Silvio Masciocchi):
- presentation and discussion of the Bridge over the Po river in Piacenza, the Cable-stayed Bridge over the Garigliano, the Cable-stayed Bridge over the Tigris in Baghdad, the Morandi method for the design of cable-stayed bridges with prestressed cables;
- geometry of the bridge decks; loads, combinations and verify; secondary elements (joints, disposal of rainwater, flooring, waterproofing); support devices;
- road bridges: viaducts, single-span bridges, cable-stayed bridges;
- setting of the overall design of a viaduct and design choices for deck, piles and wing walls;
- pre-designing of a prestressed deck, a mixed steel-concrete section, in steel as an orthotropic plate.
- formation of designing groups and assignment of project work.
