7. Steel columns – principles of structural solution, basic principles of design.
8. Application of steel-concrete structural members and segments in the constructions, examples of realised constructions.
9. Combined structures on a base timber-concrete – principles of structural solution, basic principles of calculations and design, principal types of timber jointing with different building materials.
10. Application of timber-concrete structures at reconstructions of floors, examples of realised constructions with utilisation of timber combination with different building materials.
11. Factors influencing design of foundations. Deep foundations. Effects of underground water. Foundations on slopes and on embankments. Foundations on loess, subsiding subsoil and volume unstable (floating) subsoil. Impact of geotechnical structures on environment.
12. Retaining structures used at architectural design of public buildings. Subsoil and water pressure stress. Stability of gravity and angular walls. Draining of walls. Swimming poles.
13. Application of geo-synthetics from the architectural viewpoint: separative, filtration, draining, protective, anticorrosive and reinforcing function. Reinforcing retaining structures, anticorrosive treatment of slopes, etc. Calculating programmes in the geotechnic: presumptions and processes in solution of the basic problems of buildings foundations. Errors at design of foundations, their sources and remedy.
