2. Célkitűzések és tanulási eredmények
2.1 Célkitűzések
The aim of this course is to introduce the materials, types, strengths and design methods of timber structures to the students. Within the scope of the subject the following topics are introduced: material models and strength grades of timber material, design of timber structural members for ULS according to EC5 (compression, tension, bending, shear, torsion, combined actions, stability analysis), design of timber structural members for SLS according to EC5 (deformations, durability, fire resistance), design of single and multiple shear plane connections with metal dowel-type fasteners (nailed and bolted connections), punched metal plate fasteners, split ring connectors and toothed plate connectors, bonded connections, design of glued-laminated timber structures, configuration and design of roof structures and lattice girders, analysis of stress concentration sites in timber structures and constructive protection methods. Improved understanding and deepening of knowledge is supported by the presentation and comparative analysis of existing timber structures.

The test is not successful if the average of two better tests is less than 50% of the available points (15 points).
3.4 Az aláírás megszerzésének feltétele, az aláírás érvényessége
No signature can be obtained from the subject.
3.5 Érdemjegy megállapítása
The final grade is determined according to the following criteria:
The final grade is calculated from the weighted average of the two better tests according to clause 3.3. Maximum 30 points can be obtained on each test. Extra points can be gained by the successful completion (≥50%) of the third (weakest) test. Extra points are calculated as 20% of the weakest (but successful) test (max. 6 points). The final grade based on the points:
GradePoints (P)
excellent (5)26 p ≤ P
good (4)22 p ≤ P ≤ 25.99 p
satisfactory (3)18 p ≤ P ≤ 21.99 p
passed (2)15 p ≤ P ≤ 17.99 p
failed (1)P < 15 p
3.6 Javítás és pótlás
There is no minimum requirement for individual mid-term benchmarking, therefore individual retake of the tests is not possible.
