Objectives
Giving methods, who make it possible for the student to calculate internal stress resultants in isostatic and hyperstatic structures under combination of permanent and mobile loads (determining enveloped lines).
To obtain insight in the behaviour of hyperstatic structures by using iterative calculation methods to become the internal stress resultants of a given permanent load combination.
To acquire insight in the importance of the deformations of concerning former calculated stress resultants.
Gaining insight in diverse calculation methods, available to determine the forces in hyperstatic structures, here enclosed, the insight to estimate the kind of chosen structure in relationship to forces and deformations.
Topics
· Non-permanent load situations.
· Cross-method.
· Calculation of deformation in isostatic and hyperstatic systems.
· Clapeyron-method.
· Summary of method to calculate hyperstatic systems.
Prerequisites
Have de disposal of the knowledge internal tension results (normal – cross – flexion) and there by caused internal stress and the related deformations in structures under external load.
Basic knowledge of the calculation methods to estimate the values for isostatic and a few of hyperstatic structures.
Knowledge of the characteristics of the section and methods for dimensioning the former forces.
Final Objectives
The student has a clear view of all the important factors in structural engineering: perception of structure (isostatic – hyperstatic), global dimensions, form and dimension of section, choice of material, kind of support, external load (solid, mobile), internal stress resultant, deformations (bending, displacements, rotation, …).
With that insight the student can predict the behaviour of structural engineering, what leads to the control calculations on the already designed structures.
With all the above factors in mind, the student should be able to design structures.
Materials used
· Teacher’s course.
· Lecture notes + exercises.
· Specialised literature.
· Eurocodes and their national application of standardisation.

Study costs
Study guidance
· Lectures
· Exercise session
Teaching Methods
On one hand lectures, on the other hand exercises in order to stimulate the creativity of the student in making choices between different kind of possible solutions.
Assessment
· Theoretical examination based on practical situation.
· Performance during exercises.
· Quoted individual exercises.
However, if a student gains a score of 7 or less on 20 on one of the different courses (parts of training items), he proves that his skill for certain subcompetencies is insufficient. Consequently, one can turn from the arithmetical calculation of the final assignment of quotas of a training item and the new marks can be awarded on consensus. Of course the examiners can judge that the arithmetic regulations mentioned in the study index card can also be used for 7 or less.
For each deviation a detailed motivation ought to be drawn up. In that case one should point out that the skill for this subcompetency is proven to be insufficient, if the student didn’t pass the partim that is considered to be important for certain subcompetencies.
