2. Objectives and learning outcomes
2.1 Objectives
The objective of the subject is the presentation of the hazards, structural reliability and their role in structural design. The behaviour of complex structures, curved steel and concrete shells, 3D truss structures and their design are introduced. The most important analytical solutions and the basics and assumptions of numerical solutions are presented. Additionally, the design methods of cable and membrane structures are concluded in the subject.

2.6 Other information
  1. Attendance to lectures and exercise classes is compulsory. The signature and credits from the subject will be refused to students missing more than what is defined in the Code of Studies of BME.
  2. Students are evaluated based on their actual individual performance. Students are required to show evidence of their own knowledge and skills. Submitting a work of others, obtaining or giving unauthorized help (e.g. during an exam or test) cheating and plagiarism in any form is unacceptable. Whoever violate the respective Regulations of the University will be given a failing grade (1), without the possibility of retake and repeat, and will be reported to the Dean’s Office.
2.7 Consultation

The instructors are available for consultation during their office hours, as advertised on the department website. Special appointments can be requested via e-mail:

II. Subject requirements

Assessment and evaluation of the learning outcomes
3.1 General rules
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via a test and examination.
3.2 Assessment methods
Evaluation formAbbreviationAssessed learning outcomes
1. midterm testMT1A.1-A.5; B.1-B.4; C.1-C.3, C.5; D.1-D.3
Written examinationEA.1-A.8; B.1-B.6; C.1-C.6; D.1-D.3

The dates of deadlines of assignments/homework can be found in the detailed course schedule on the subject’s website.
3.3 Evaluation system
Total achievable during the semester20%
Criterion for completion of the subject is to collect at least 50% of the total points of the Test. Moreover, unsatisfactory performance during the Exam will lead to a final mark 'failed' (1) independently of the result of the Test.
3.4 Requirements and validity of signature
Criterion for the signature is to collect at least 50% of the total points of the Test according to Section 3.3.
If the applicant does not take the examination course with an earlier acquired signature, his or her points are overwritten by his or her new points.
The previously acquired point can be taken into account in the next 6 semesters.
3.5 Grading system
GradePoints (P)
excellent (5)80<=P
good (4)70<=P<80%
satisfactory (3)60<=P<70
passed (2)50<=P<60%
failed (1)P<50%
3.6 Retake and repeat
  1. The midterm test can be repeated – once without fee – at a previously determined date given in the course schedule.
  2. In case of repetition of the test, the better result will be taken into account for the calculation of the final mark.
  3. If the first repetition is also unsatisfactory (failed), then the test can be repeated once more on the repetition week by paying a fee.
