AF2201 Bridge Design 7.5 credits

• The history of bridge construction.
• Different bridge types and their structural behaviour.
• Loads and load distribution on bridges.
• Influence lines.
• Analysis and design of composite bridges.
• Analysis and design of arch bridges.
• Analysis and design of cable supported bridges
• Analysis and design of pre-stressed concrete bridges
• Conceptual design of a road bridge is included in the course as a project task

This course deals with planning and design of both simple bridges such as beam type bridges as well as other more complicated bridge structures such as arch bridges and cable supported bridges. Conceptual design of a road bridge is included in the course as a project task.

The aim of this course is to give basic knowledge on planning, analysis and design of bridges. After this course, the student will be able to:

• Classify different types of bridges.
• Calculate loads, lane factors, load cases and load combinations.
• Develop and use influence lines for bridge analyses.
• Explain the behaviour of beam type, composite, pre-stressed concrete, arch, and cable supported bridges.
• Create idealized models for analysis and evaluate forces and moments.
• Evaluate forces and moments considering large displacements. (2nd order theory)

If the course is discontinued, students may request to be examined during the following two academic years.

• BER1 - Project, 3.0 credits, grading scale: P, F
• TEN1 - Written examination, 3.0 credits, grading scale: A, B, C, D, E, FX, F
• ÖVN1 - Exercises, 1.5 credits, grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.
