Objectives
Introduction to the use of steel and other metals as building materials;
Classification of steel according to chemical structure, to application possibilities, to sizes, dimensions and tolerances of the products;
Making the student familiar with:
- mechanical and thermal processing of steel components;
- problems as corrosion, and the means to prevent or to solve them;
- dimensioning of profiled beams and other structural components under current loads, with special attention to torsion;
- technology of the connections in steel structures;
- the important topic of the durability of steel structures, and the measures to be taken in the stage of design, manufacturing and erection.
Developing skills with respect to the calculation and dimensioning of welded joints.
Topics
METAL CONSTRUCTION:
Part 1:
Generalities; production of steel; characteristics; thermal, chemical and mechanical processing; properties;
Classification of steel according to chemical structure, to application possibilities, to shape, size, dimensions and tolerances of the building-products.
Part 2:
Steel for current use in steel construction; chemical structure; mechanical properties: strength, toughness, ductility, hardness; stress and strain;
Trade products of rolled steel and appliance: hot and cold rolled profiles, plate products;
Mechanical processing;
General and local corrosion; rust; removing, preventing and protection.
Part 3:
Calculation of profile metals and other structural elements; allowed stresses and deformations; yield-criterion; load types and combinations: traction, compression, instability, shear, bending, torsion;
Part 4:
Technology of connections in steel structures;
Welded joints: welding techniques, specifications, residual welding stresses, recommendations for design and manufacturing, calculation, design criteria in case of static and dynamic actions;
Connections made with bolts, rivets and pins.
Prerequisites
Final objectives of STABILITEIT 1.
Mechanics of materials.
Final Objectives
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.
