Objective

On completion of the course the student can
• Discuss the use of wood as a building material.
• List the significant material properties of wood and their magnitude.
• Compare the material properties of wood with those of other building materials.
• Estimate how the moisture content of wood influences strength.
• Estimate the effect of load duration on the behaviour of the structure.
• Define load combinations of an ordinary timber beam.
• Perform ULS design of a beam to comply with EN 1995-1-1. Consider the influence of lateral buckling to the moment capacity of a beam under bending moment.
• Define the capacity of a simultaneously compressed and bent structural member considering also the possibility of buckling.
• Derive deformations considering the influence of creep.
• Calculate the capacity of a nailed joint.
• Calculate the deformation of a nailed joint.
• Define the stresses in a cross-section consisting of multiple materials.
• Calculate the deflection of a beam consisting of multiple materials with varying creep properties.
• Perform the ULS and SLS design of a glued I-section.
• Perform the ULS and SLS design of a tapered beam.
• Perform the fire design of a timber structure.
• Perform a vibration check for a timber floor according to the Finnish National Annex of EN 1995-1-1.
• Consider how capacity is influenced in mechanically formed members by deformation in the joints.
• Design structures of wood based building boards.
