BYG300 Timber Structures and Structural Analysis

Course description for academic year 2020/2021

Due to Covid-19, changes may occur in course descriptions for the autumn semester of 2020. Changes in each course will be published on Studentweb or Canvas. When a course description has been changed there, the description on web is no longer valid. Examples of such changes could be accomplishment of practice, course type, or whether letter grades or passed/not passed will be used as grading scales.

Contents and structure

The course will provide an understanding of the behavior of timber structures, placed in a building context. The course will provide the basis for the design of simple timber structures.


  • Characteristics of wood as structural material
  • Design calculations for axial force, torsion, moments and shear force
  • Buckling effects
  • Special calculation rules for load distribution, stiffening, composite cross sections, etc.
  • Calculation of displacements
  • Structural design of connections: nails, screws, bolts, timber connections, dowels
  • Review of relevant "Byggforsk" sheets
  • Fire resistance
  • Cross Laminated Timber

The course will also provide an understanding of the behaviour of structures in general and will provide a basis for structural analysis.

  • Energy methods (Castigliano's theorem)
  • Deformation of beams, frames and truss structures
  • Statically indeterminate beams, frames and truss structures
  • Plastic design methods (collapse of frames)
