2. Célkitűzések és tanulási eredmények
2.1 Célkitűzések
Lectures of Steel Structures have the general aim to study the basics of the design of steel structures, which consists of the design of simple structural members, simple joints and the investigation of the basic failure phenomenon, which can occur in steel structures. The students get knowledge in the following topics: steel grades, mechanical properties of the steel material; calculation of cross-sectional properties; design of centrically loaded tension members; design of centrically loaded compression members; buckling problem – behaviour – design method; design of beams: construction, behaviour under bending and shear interaction; beam structural behaviour - design approaches for lateral torsional buckling; design of bolted connections; design of welded connections; fatigue design and brittle fracture; plate buckling phenomena, basics of the cross-section classification.

3. A tanulmányi teljesítmény ellenőrzése és értékelése
3.1 Általános szabályok
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via midterm tests, home works and attendance on the lectures.
3.2 Teljesítményértékelési módszerek
| Evaluation form | Abbreviation | Assessed learning outcomes |
| 1. midterm exam (summary evaluation) | MT1 | A.1-A.3; B.1-B.2; C.1-C.3; D.1 |
| 2. midterm exam (summary evaluation) | MT2 | A.4-A.5; B.3-B.4; C.1-C.3; D.1 |
| 3. midterm exam (summary evaluation) | MT3 | A.6-A.8; B.5-B.6; C.1-C.3; D.1 |
| 1-3 home work | HW | A.1-A.8; B.1-B.6; C.1-C.3; D.1 |
| attendance and activity (optional; positive only) | A | A.1-A.8; B.1-B.6 |
A szorgalmi időszakban tartott értékelések pontos idejét, a házi feladatok ki- és beadási határidejét a "Részletes féléves ütemterv" tartalmazza, mely elérhető a tárgy honlapján.
3.3 Teljesítményértékelések részaránya a minősítésben
| Abbreviation | Score |
| MT1 | 34% |
| MT2 | 34% |
| MT3 | 34% |
| HW1 | 5% |
| HW2 | 5% |
| HW3 | 5% |
| A (bonus) | 17% |
| Sum | 100% |
- All midterm exams have theoretical and practical parts.
- Two midterm exams should be completed ≥ 50% among the three midterms, theoretical and practical part separately.
- The best two theoretical and practical parts are not necessarily from the same midterms (e.g. MT1 and 3 theories and MT2 and 3 practices are the two bests).
- Home works are optional.
- The aim of the home works are the preparation for hte practical part of the midterms. They are parametric practical examples, unique for each students.
- Max. 15 points are gained by Home works.
- By completing the third midterm (less gained points) successfully (≥50%) bonus points are gathered.
- The theoretical and practical parts of the third midterm (less gained points) max 7 and 10 points are gathered.
