Wood based composites, solid wood, glued laminated timber, cross-laminated timber, cross-ply and compositions of those. Design rules for composite structures. Stress peaks (hot spots) around holes in beams and plates and reinforcements.
Long time properties, moisture and shape distortions, creep and relaxation. Pre-stressed components.
Dynamic loading, vibrations and fatigue.
Fire and design of timber structures.
Timber Structures 1 gives a basic introduction to design of timber structures and is a prerequisite for Timber Structures 2. Timber Structures 2 deals with the more advanced topics related to the design and calculations of timber structures. The theoretical foundation for modeling of wood and timber structures by use of the finite element method will be established. The aim is to understand the structural behavior of composite structures made out of anisotropic plates and shells, as well as to compute the structural response. Joining techniques with respect to their capacity and stiffness will be studied. Furthermore, analytical methods together with design rules will be studied for composite structures or special structural details. Time dependent effects and fire design are also be included.
The students shall have knowledge about:
- Numerical modeling of wood and wood-based materials and composites for use in load-carrying structures
- Joining techniques for wood-based materials and their properties
- Time-dependent effects important for design of wooden components
- Response of timber structures exposed to dynamic loading
- Fire design
The students shall be able to:
- evaluate and propose effective use of wood-based components for use in load-carrying structures
- model and compute the structural response to loading by use of numerical simulations and analytical methods
- verify that all requirements to structural design are fulfilled with respect to European design rules (Eurocode 5 parts 1-1, 1-2 and -2)
The students shall master:
- general basis of load and load calculations
- general static analysis and calculation of load effects
- general basis of structural design according to European rules
Learning methods and activities
Lectures, demonstrations and exercises. 2/3 of the assignments must be approved prior to the examination. The lectures and exercises are in English when students who do not speak Norwegian take the course. If the teaching is given in English the Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
Further on evaluation
If there is a re-sit examination, the examination form may be changed from written to oral.
Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
