AF2213 Steel and Timber Structures 7.5 credits

Design calculations are, within the steel part of the course, carried out according to Eurocode 3. The calculations deal with such things as:

• Local buckling for ordinary steel profiles
• Bending resistance of ordinary steel profiles
• Design of steel columns with regard to flexural column buckling
• Design of steel beams with regard to shear and patch loading
• Bolted joints, analysis and design
• Welded joints, analysis and design
• Design of steel beams with reference to lateral torsional buckling
• Technology of thin walled steel profiles, especially instability problems

Design calculations are, within the timber part of the course, carried out according to Eurocode 5. The calculations deal with such things as:

• Moment and shear force resistance of glulam beams having straight, tapered and curved shapes
• The influence of large holes and notches in timber beams
• Design of timber joints in which mechanical connectors such as nails and bolts are used
• Design of timber beams and columns sensitive for flexural buckling and lateral torsional buckling
• Design of timber beams having flanges of timber and webs of wood based panels
• Design of stressed skin elements have flanges of wood based panels
• Design of beams made of two different materials where we have partial composite action between the parts

The overall goal of the course is to give detailed knowledge about analysis and design of common structural elements of steel and timber. After having passed the course the student should be able to:

• Calculate the bending and axial resistance of steel beams with regard to local as well as global instabilities
• Explain the effect of shear and patch loading on the resistance of steel beams
• Calculate the resistance of common bolted connections for steel structures
• Explain the static behaviour of different types of welded joints in steel structures
• Calculate the load bearing resistance of beams subjected to lateral torsional buckling
• Understand specific problems related to the design of thin walled steel beams, especially the interaction between local buckling, distortional buckling and global buckling
• Perform adequate design calculations for straight, tapered and curved beams of glued laminated timber (glulam)
• Understand how large holes and notches influence the shear resistance of timber beams
• Perform design calculations for nailed and bolted connections in timber structures
• Understand how instabilities such as flexural and lateral torsional buckling influence the resistance of timber beams
• Perform design calculations for elements made of wood based panels, especially with regard to buckling
• Understand the theory of partial composite action for beams made of timber, possibly in combination with other materials such as steel

Documented knowledge in Structural Mechanics and Structural Engineering equivalent to at least 3·times 7,5 ECTS corresponding to the content in courses AF1006, AF1005 and AF2003.

Eng B/6 according to the Swedish upper secondary school system.

Documented knowledge in Differential Equations corresponding to the content in course SF1676 Differential Equations with Applications.

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

• TEN1 - Examination, 4.5 credits, grading scale: A, B, C, D, E, FX, F
• ÖVN1 - Exercises, 3.0 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.

TEN1 Written exam 4.5 credits

ÖVN1 Exercises 3 credits

All parts need to be passed.

The final grade depends only on the examination results.
