Professor
Emanuele MaioranaLearning objectives
The aim of the course is to provide the basic knowledge of construction techniques applied to bridges, using the national and European technical standards, necessary for drawing up the design of a single span simply supported bridge.
It also deals with applicable solutions for reducing seismic risk in the context of bridge structures.
The transversal load distribution is addressed by applying literature methods, comparing them with the results of a FEM approach.
Course content
The course consists of the treatment of the following macro-topics.
• Bibliography references on bridge construction techniques.
• Structural typologies of bridges (static diagrams and constituent elements).
• Materials and technologies (steel, composite, wood and masonry)
• Examination of the parts of the national and European technical standard on bridge design.
• Actions on the structure.
• Transverse distribution criteria of mobile loads on the deck and comparison of the same with numerical analysis using FEM models.
• Use of influence lines to determine stresses on isostatic and hyperstatic structures (continuous decks on multiple supports).
• Structural checks, according to SLU / SLE:
- resistence
– stability
- fatigue
– deformations
– bolted/welded joints
• Seismic risk reduction technologies applicable to bridge structures.
• Operational aspects of construction and assembly.
• Case studies (collapse mechanisms).
• Annotated drafting of a scaffolding project:
– orthotropic plate
– mixed steel-concrete section
– with reinforced concrete beams
– on the catwalk
• Considerations on controls, maintenance and durability.
• Seminar with designers/builders.

Teaching methods and tools
The methodologies used within the course consist of the exposition of basic concepts through lectures and the carrying out of exercises.
Below is basic information about the teaching method:
• teaching strategies: carrying out exercises, using FEM codes, drafting a bridge project;
• attendance: optional, but highly recommended;
• delivery method: in digital format;
• language: Italian/English.
Assessment methods and criteria
The level of learning acquired by the students is assessed through the analysis of the exercises on the topics covered during the lessons.
To take the exam it is mandatory to complete and submit the bridge project assigned during the course in a timely manner.
Detailed information about the exam will be provided during the course; indicatively:
– method: oral exam;
– times: at the end of the course;
– duration: approximately 30-60 min.;
– return of the result: immediately after the test.
It is not permitted to consult material (books, notes, etc.) during the test.
