2. Objectives and learning outcomes
2.1 Objectives
The objective of the subject is the modelling of beams, membrans, plates and the simplest circular shell structures. The most important analytical solutions, the basics and assumptions of numerical solutions are introduced. It’s presented that the different structural considerations can be implemented in the design codes and regulations. The fundamental membrane solutions, shear lag effect, effective width, shear deformation, second-order effects and large deformations, anisotropy and the vibration of floors are also analysed. The main focus of the subject is the analysis of plates and slabs.

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 tests and the examination.

3.4 Requirements and validity of signature
The midterm tests are unsatisfactory if the average points of the two best tests is less than 50% of the achievable points.
Obtaining less than 40% of the achievable points on the exam, or reaching less than 50% of the total points will lead to a final mark 'failed' (1).
Criterion for the signature is to successfully fulfil the criteria of the midterm exams detailed in point 3.3 and the student obtains at least 50% of the total achievable points during the semester. No points are given for the homework submitted after the deadline (homework submission is not compulsory).
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.
