PARTIM GEOTECHNICS 1:
*Introduction, historical background and description of soil: geological description - rocks - stone - gravel - sand - silt - loam - peat - ...
*Geotechnical characteristics and classification of soils.
*Previous investigation, use of data, research in situ, soil testing and description of soils: grain-size distribution - density and compaction of sands - determination of the plastic limits - triaxial tests - CPT-tests - boring tests.
*Stresses and strains in soils: total and effective stresses and the effects of ground water pressure and consolidation.
*Shear strength of soil (labo- and in situ tests).
*Settlement criteria of soils (labo- and in situ tests).
*Shallow foundations: distribution of stresses in the plane between soil - foundation (base foundation surface).
*Shallow foundations: bearing capacity and settlement.
*Practical calculation of bearing capacity and settlement.
*Eurocode 7.

Final Objectives
PARTIM METAL CONSTRUCTION:
General scientific competences:
Insight in basic concepts of Probability and Statistics must be used to determine representative values of material properties and relevant values and combinations of the actions on the steel structure.
General technical competences:
The student must have acquired insight into the impact of chemical, thermal and mechanical processing on the steel properties and its appliance, in order to be able to select in a judicious way the right sort of steel for the right purpose;
Specific competences:
Acquisition of new concepts: killed steels, quenching and self-tempering, heat affected zone, residual welding stresses, alloying by precipitates;
Acquisition of new insights: the mechanism of local corrosion; effects of residual stresses;
Developing new skills:
- Dimensioning of profiled beams and other structural components under current loads;
- Appropriate use of the available standard profiles;
- Decent design of welded connections;
- Prevention and solution of problems related to the stability or durability of steel structures on long terms, by taking measures in the stage of design, manufacturing or construction.
PARTIM GEOTECHNICS 1:
Basic understanding of Soil Mechanics, i.e. the mechanical properties and behaviour of soils during forces from geotechnical constructions, as building foundations.
Starting from CPT (cone penetration tests) and the initial loads coming from the structures, design shallow foundations and control the bearing capacity and calculate the settlement.

Assessment
Evaluation during examination period:
PARTIM METAL CONSTRUCTION: 50%
Oral examination after written preparation.
PARTIM GEOTECHNICS 1: 50%
Oral examination based on the know how of the design and the calculation of shallow foundation.
Individual exercises based on the results of CPT-tests (download on DOV).
A weighted average is used to compute the final score for a training item. 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.
