After successful completion of the course, students are able to use calculation models to reflect the load-bearing behavior of steel structures. They understand the process chain for manufacturing and assembling steel structures to be able to design them. This enables them to dimension structural steel components or evaluate existing structures.
The calculation models and methods for describing the load-bearing behavior and for verifying the load-bearing capacity of cross-sections and members include the following topics:
- Determination of internal forces according to first-order and second-order theory for statically determinate and indeterminate systems
- Elastic stress determination for combined effects of stress resultants from normal force, bending moment about two axes, and torsional moments due to St. Venant torsion
- Determination of the stresses due to warping torsion as a result of torsional loads on members with typical steel cross-sections and superimposition with other loads
- Determination of the plastic cross-section bearing capacity by deriving interaction models for combined effects of shear force and bending moment (each about both bending axes) and normal force
- Global member stability problems: flexural buckling, torsional buckling, and torsional flexural buckling and their interaction
- Stability problems for polar and non-polar normal force effects
- Local stability problems: normal stress buckling, shear stress buckling
- Cross-section analyses with consideration of local stability problems in the interaction of normal force, shear force, and bending moment
- Load-capacity analyses in the event of stability problems with global and local stability threats
- Determination of the load-capacity of screwed and welded connections as well as hybrid connections
- Determination of the damage-equivalent in the case of fatigue actions using the reservoir method and evaluation of load collectives.
- Methods for analyses of steel structures for the serviceability and ultimate limit states without and with fatigue.
The students are able to design the following steel structures by applying the subsequent topics:
- Criteria for steel constructions suitable for production, welding, transport, assembly, corrosion protection, testing, and maintenance
- Design principles for standard cross-sections (open, closed) of haunched and non-haunched beams or columns, butt joints for beams and columns, support details, base point details, beam crossings, column-beam connections, frames, trusses, frame trusses
The students can develop calculation models to be able to describe the flux of forces for verification purposes for the following constructions:
Typical cross-sections for haunched and non-haunched beams or columns, butt joints for beams and columns, support details, base point details, beam crossings, beam supports, column-beam connections, frames, trusses, frame trusses, truss nodes
