Course abstract

Wood as a building material is a logical choice in todays world. In order to ensure rational use of materials and other elements, it is necessary to be familiar with their production technology, usage and properties. It is also necessary to be familiar with other related products and their properties and usage. This knowledge is crucial not only for structural engineers, but also for everyone involved in the process of building with wood.

Learning outcomes and their assessment

Knowledge.
Classify and explain types of construction timber materials, structures and fasteners, their manufacturing processes, properties and relevant requirements.
Assessment: test.
Skills.
Choosing materials, types of structure and fasteners for timber construction. Skills for applying them in coordance with relevant requirements, standards and recommendations.
Assessment: test and practical assignment.
Competence.
Assess and analyse changes in rules, standards and recommendations, perform detalisation of project in coordance with rules, standards and recommendations. Seeking and finding non-compliances in projects and prevent them.

Criteria for Evaluating Learning Outcomes

Test No. 1.
Student is presented with and example of simple structure. Student has to select the most appropriate technological solution (materials, fasteners). Assignment is done as a sketch with attached annotations for each of the chosen elements.
Grade consists of the following:
Material choice – 30%.
Fastener choice – 30%.
Constructive argumentation of the selection – 40%.
Test No. 2.
Student is presented with three connections. For each of the connections information about the materials, loads and other limitation is provided. Student is to select fasteners and make technical drawing and bill of materials in coordance with requirements and relevant normatives.
Grade consists of the following:
Choice of fasteners – 30%.
Application of fasteners in coordance with relevant requirements and manufacturers recommendations – 30%.
Correctly done technical drawings – 30%.
Correctly done bill of materials – 10%
Practical assignment.
Student is presented with design task.
Student develops a building project.
Grade consists of the following:
Choice of structure and fasteners – 50%.
Correctly formatted drawings – 30%.
Oral presentation of project – 20%.
