Course abstract

This course brings together the latest developments in timber engineering. The core units for the course are: new wood materials and products, new fastener types and research of behaviour of joints, stress-strain analysis of heavy loaded elements, sustainable and energoeffective structures of wood products. Design topics are taught in accordance with structural Eurocodes with extension of topic for robustness, promoting high intelligence and competence of specialist; as well as emphasising on the discussion and criteria for decision making when problem needs to be solved.

Learning outcomes and their assessment

• Knowledge and understanding on contemporary approach to developments in wood materials and products using effective investigation methods. • Skills: for analytical and experimental research of stress-strain relationships and behaviour of joints. Presentation • Competence: to demonstrate an ability to put in use the knowledge and skills for problem solving in structural timber design and research. Presentation, examination

Requirements for awarding credit points

Examination is established as a discussion on two issues:
1) new wood materiāls and products,
2) design of robust and sustainable structures.

Description of the organization and tasks of students’ independent work

1st Presentation: Wood materiāls and prefabricated building products: newest investigations and results
2nd Presentation: Problems and solutions in design and execution of robust and sustainable structures.

Criteria for Evaluating Learning Outcomes

Assessment of examination is obtained as average of results of two presentations mentioned before with the topic related discussions.
