Architecture with timber-based hybrid structures.

On completion of the course, the student should:

• Understand the physical and mechanical behaviour of different wood species and wood-based materials.
• Have general knowledge of the physical and mechanical behaviour of some materials which can be used in combination with wood.
• Understand both possibilities and limitations of timber when used in structures.
• Understand, analyse and design wood-based hybrid components.
• Understand, analyse and design wood-based hybrid systems.
• Gain knowledge about connection techniques for timber-based hybrid members and structures.
• Be able to analyse and design timber-based hybrid components with partial and complete composite action.
• Be aware about possible failure modes of hybrid structures.

Scientific articles, reports and supplementary literature are available on Learning Management Systems, LMS, during course.

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

• LAB1 - Lab work, 1.0 credits, grading scale: P, F
• PRO1 - Project work, 3.5 credits, grading scale: P, F
• TEN1 - Written exam, 2.0 credits, grading scale: A, B, C, D, E, FX, F
• ÖVN1 - Exercise, 1.0 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.

Passed project assignment, exercises, laboratory part and written examination.
