Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Chapter 1 : Steel characteristics and durability
Chapter 2 : Design of steel frames
Chapter 2 : Design of steel frames
- Modelling and simplifying assumptions ;
- Bracings and dilatation joints;
- Design of one storey structures (type « hall » - monovolumes) ;
- Design of multi-storey structures (type « building») ;
- Main typologies of high rise buildings ;
- Classification of frames.
- Classification of the sections
- Section resistance and associated dimensioning criteria (pure tension, pure compression, pure bending, composed bending, bi-axial bending, shear, ') ;
- Extension of the dimensioning criteria to take into account the instabilities as buckling, lateral-torsional buckling and second order effects ;
- Application to hot rolled sections;
- Presentation of particular structural elements : welded fabricated sections (PRS) with or without reinforcing flange, beams with holes (Angelina), truss beams, thin walls sections.
- Properties and classification of the welds, resistance criteria for welds under tension, shear and combined loads;
- Basic calculation of simple welded connections ;
- Properties and classification of the simple and prestressed bolts, boulons normaux et précontraints, resistance criteria for bolts under tension, shear and combined loads ;
- Resistance of the connected elements
- Design principles of moment resisting connections, basics of stiffness, resistance, rotation capacity, semi-rigid connections.
- Calculation of the degree of connections of the slab to the steel beam, full connection, effective collaborating width, behaviour of the composite beams and composite slabs with and without steeldecks, evaluation of the plastic moment.
- Resistance to fatigue, actions, effects of random stresses, damage accumulation, fatigue security checks, basics of fracture mechanics.
- Thermal analysis, heating of composite steel-concrete elements, mechanical hot resistance, general principles of a « fire design » of a steel and steel-concrete structure ;
-
Practical means of protection against fire.
Teaching methods
