Bridge Constructions
Teacher
Credits
6 CFU
Objectives
Reinforced concrete, pre-stressed concrete and composite steel-concrete bridges. Finite element modelling of bridges. Design of piers, abutments and foundations. Structural bearings, expansion joints and anti-seismic devices. Bridges retrofitting.
Acquired skills
The students will be able to design reinforced concrete, pre-stressed concrete and composite steel-concrete bridges. The students will also be able to design retrofitting of existing bridges.
