Aim
The course gives applicable knowledge of the design of bridges.

Knowledge and understanding
For a passing grade the student must

• be able to analyse bridge structures with regard to traffic and other relevant actions and understand analysis methods specific for bridge design.

• understand the behaviour of pre-stressed concrete structures and design methods used for bridges.

• have knowledge of different bridge types and their respective construction method.

Skills and abilities
For a passing grade the student must

• be able to apply knowledge from previous courses in design project for bridges.

• be able to independently choose type of bridge, structural layout and construction method early in the design stage.

• be able to present the results from the design both in writing and as drawings.

• be able to independently find a critically evaluate the information about technical solutions for bridges.

Judgement and approach
For a passing grade the student must

• be able to independently evaluate different types of bridges and structural solutions reviewed in the literature and given in lectures.

• be able to independently adjust and modify standard solutions to a specific project.

Contents
The course includes lectures, design projects, visiting lectures by professional bridge designers and a study visit.

The course is based on two major projects. The first project is a conventional two span road bridge in pre-stressed concrete. The design is made on a relatively detailed level. The second project is a long span bridge where the structural system, construction methods, economy and aesthetics are chosen in the form of preliminary design level.
