Code

CE-TIM1

Version

3.0

Offered by

Civil Engineering

ECTS

Prerequisites

Basic knowledge about structural design, which includes as minimum
• understanding of the concept of normal stress, strain, strength of material , bending , shear force/stress.
• knowledge about Eurocode 1990 and 1991, load combinations
• knowledge about ultimate limit state and serviceability limit state
• understanding of different load transferring functions regarding the transferring of vertical and horizontal loads in a structure.
• ability to find internal forces for determinate/indeterminate beams/columns.

Main purpose

The purpose of the course is to enable the student gain basic understanding of fundamental properties of the material Timber. The purpose of the course is also to enable the student to design more advanced timber structures as well as more common connections in timber.

Knowledge

After completion of the course, the students must:
– have knowledge about fundamental properties of materials in Timber.
– have basic knowledge about Stress analysis and calculation of deformation of simple load-bearing structures.
– have knowledge and understanding of the most complex load bearing structures and connections in timber.
- Have knowledge about CO2 Emission from wood.

Skills

After completion of the course, the students must:
• have gained an understanding of Timber structure and physical properties.
• be able to apply their knowledge in order to carry out stress analysis and calculation of deformation of simple load-bearing structures in timber beams and centrally loaded timber columns.
• be able to describe materials of Timber based panels
Also they must be able to describe, calculate and apply:
• Moment loaded compression bars in timber.
• Lateral torsional buckling in timber beams.
• Connections in timber structures – nails and bolts.
• Tension/compression bars
• Tapered beams.
• Trusses and glued thin-flanged beams.
• Fire resistance calculation.
• Diaphragms in timber structures.
• be able to calculate CO2 emission from wood to help with comparison.

Competences

After completion of the course, the student must be able to use knowledge and skills within all subject areas to plan and make relevant choices of techniques and theories in order to solve structural design project.
The students must also be able to perform laboratory experiments and associated reports (laboratory exercises are conducted as a workshop courses).

Topics

Teaching methods and study activities

The course is scheduled for 12 weeks with 4 lectures each week. Workload for the students corresponds to 137,5 hours.
The course will include theory concerning the mentioned subjects supplemented with exercises and obligatory course assignments.
