Bridges design and construction
Academic Year 2022/2023 - Teacher: PIER PAOLO ROSSIExpected Learning Outcomes
The course aims to :
- provide knowledge regarding the historical development of bridges and types commonly used in structural engineering
- provide knowledge regarding the construction techniques of bridges
- provide knowledge regarding the actions on bridges
- provide knowledge regarding the main theoretical models applied to the structural analysis of bridges
- provide knowledge regarding the design of bridges, in view of present codes
- provide knowledge regarding the assessment of damage of existing bridges.
Course Structure
Frontal teaching: theoretical lessons and classroom exercises.
If teaching is given in a mixed or remote mode, the necessary changes with respect to what has been declared may be introduced, in order to comply with the program envisaged and reported in the syllabus.
Required Prerequisites
Basic knowledge regarding :
- Structural mechanics
- Design of structures
Attendance of Lessons
Attendance to lessons is strongly recommended as it is consistent with the proposed training model, which aims to encourage gradual learning, active participation of the student in the classroom and dialogue between teachers and students.
Attendance is also recommended as the teacher is expected to carry out design exercises in the classroom.
Detailed Course Content
Theoretical lessons:
- Historical development of bridges
- Types commonly used in structural engineering: girder bridges, rigid-frame bridges, arch bridges, cable-stayed bridges and suspension bridges
- Parts of the bridge: deck, piers, abutments, bearing devices, expansion joints etc.
- Codes regarding design and construction of bridge
- Loads on bridges
- Design of bridges with composite decks
- Influence lines and infleunce surfaces
- Uniform and non-uniform torsion in bridge decks
- Local instability in steel girders
- Bearing devices
- Design of foundations, piers and abutments
- Seismic design of bridges
- Constructional techniques
- Methods for the assessment of damage of existing bridges
Practical lessons:
- Design of bridges with composite steel-concrete decks (reinforced concrete slab, longitudinal steel girder, tranverse beams, bearing devices and piers)

Learning Assessment
Learning Assessment Procedures
The gradual learning of the topics covered in the course
will be assessed by the teacher following the corrections of the project work and following the student's participation in class discussions.
The final assessment will be carried out on the basis of the project work and by means of an oral exam on the topics of the course.
Note: the verification of learning can also be carried out in remote, should the conditions require it
Examples of frequently asked questions and / or exercises
- Traffic loads on bridges
- Theory of Courbon
- Flexural verification of steel-concrete composite bridge beams
- Design of shear studs in steel-concrete composite bridge beams
- Shear verification of steel-concrete composite bridge beams
- Lateral torsional stability verification of steel-concrete composite bridge beams
