|101-0138-00L||Bridge Design||6 credits||4G||W. Kaufmann|
|Abstract||This course presents the fundamentals of bridge design. It covers the entire range from conceptual design to construction, encompassing all relevant building materials. The focus lies on the structural behaviour of today’s most important bridge typologies and their suitability for certain boundary conditions, the dimensioning of the main structural elements as well as construction methods.|
|Objective||After successful completion of this course, the student should be able to:|
- Define the main bridge design parameters and identify constraints and boundary conditions
- Explain the structural behaviour and peculiarities of today’s most important bridge typologies
- Explain the main elements of bridges and their structural behaviour
- Define the relevant actions on bridges
- Dimension a standard bridge (pre-dimensioning by hand; dimensioning using computer-aided tools)
- Explain the most relevant bridge construction and erection methods
- Select an appropriate typology and conceive a convincing bridge for a site with its specific boundary conditions
- Name the most eminent bridge designers and their relevant works
|Content||The course is built up as follows:|
2. Conceptual design
3. Superstructure / Girder bridges
4. Support and articulation
6. Arch bridges
7. Frame bridges
8. Special girder bridges
9. Cable-supported bridges
The course is complemented by
- Guest lectures by leading bridge designers active in industry
- Inverted classroom exercises on conceptual bridge design
- Slides on eminent bridge designers and their works
- Exercises (homework)

|Prerequisites / Notice||The course is part of the MSc specialisation in structures and requires solid knowledge in structural analysis and design. Students are assumed to be proficient in the material taught in the following courses offered in the BSc in Civil Engineering at ETH Zurich (or have acquired equivalent knowledge elsewhere):|
- Theory of structures I+II
- Steel structures I+II (incl. steel-concrete composite structures)
- Structural Concrete I+II (incl. prestressed concrete)
The flipped classroom exercises are preparing the students for Part 1 of the exam (conceptual design). Active participation is highly recommended to all students who have not conceived a bridge.
|101-0138-11L||Bridge Design: Project Competition |
Number of participants limited to 20.
All students get on waiting list. Final registration based on application letter (information given in first lecture). Priority will be given to students attending “Bridge Design (101-0138-00 G)” and in the primary target group (Major in Structural Engineering or Projektbasierte Lehrveranstaltungen).
|4 credits||2S||W. Kaufmann|
|Abstract||This module offers the possibility to apply the fundamentals of the course Bridge Design in a conceptual design project. The scenario is set as a design competition: The students (group of two) will get a basic documentation (service criteria agreement, plans, digital terrain model, geotechnical report, photo documentation, etc.) and will develop a conceptual design suitable for the given site.|
|Objective||At the end of the course, students will have developed a convincing bridge design that satisfies following criteria:|
_ Consideration of governing boundary conditions and constraints.
_ Conception of an efficient structural system with an adequate aesthetic expression considering the environment.
_ Definition of the relevant actions and decisive load cases.
_ Proof of feasibility by dimensioning the main structural elements.
_ Schematic overview of construction processes.
_ Appropriate presentation and visualisation of the proposed bridge design.
|Content||The module is built up as follows:|
0. Presentation of problem statement / project. (1st week of semester)
1. Team registration (teams of two students).
2. Issue of documents.
3. Introduction to design tools & working methods.
4. Working on project (milestones):
... a. Define requirements and boundary conditions.
... b. Study of references and possible concepts
... c. Choice of best variant
... d. Structural modelling & calculations
... e. Plans & visualisation
|Prerequisites / Notice||It is highly recommended to attend the course “Bridge Design (101-0138-00 G)” simultaneously.|
