Experimental Investigation on SFRC behaviour under elevated temperature
Autor: Goremikins V.; Blesák L.; Novák J.; Wald F.
(Multi-Science Publishing Co Ltd, 2017)Steel fibres being added to a concrete mixture lead to an overall improvement of such a mixture considering several factors, such as mechanical resistance, fire resistance, creep stability and other. Besides steel fibres, ... -
FIRE-PROTECTION WITH ALKALI-ACTIVATED CEMENT BINDER
Autor: Šejna J.; Šmilauer V.; Šulc S.; Wald F.; Reiterman P.
(University of Ljubljana, Faculty of Civil and Geod, 2021)Fire resistance of unprotected steel structures is very low and steel elements must be protected from fire. One possibility is to create a protective layer of a cement-based material. Most types of cement have a low ... -

Autor: Tretyakov A.; Tkalenko I.; Wald F.; Novák J.; Štefan R.; Kohoutková A.
(IOP Publishing Ltd, 2017)The recent development in technology of production and transportation of steel fibre-reinforced concrete enables its utilization in composite steel-concrete structures. This work is a part of a project which focuses on ... -
Heat transfer in hybrid fibre reinforced concrete-steel composite column exposed to a gas-fired radiant heater
Autor: Štefan R.; Procházka J.; Novák J.; Fládr J.; Wald F.; Kohoutková A.; Scheinherrová L.; Čáchová M.
(IOP Publishing Ltd, 2017)In the paper, a gas-fired radiant heater system for testing of structural elements and materials at elevated temperatures is described. The applicability of the system is illustrated on an example of the heat transfer ... -
Lateral-torsional buckling of class 4 section uniform and web tapered beams at elevated temperature
Autor: Jandera M.; Prachař M.; Wald F.
(Elsevier B.V., 2020)An extensive numerical study of Class 4 section beams at elevated temperature is described in the paper. The study focuses on welded I-section beams of slender web and flange and covers beams of constant height as well as ... -
THE STEEL AND FIBRE-REINFORCED CONCRETE CIRCULAR HOLLOW SECTION COMPOSITE COLUMN EXPOSED TO FIRE
Autor: Tkalenko I.; Tretyakov A.; Wald F.; Novák J.; Štefan R.; Kohoutková A.
(Ernst & Sohn, 2017)The recent development in technology of production and transport of the steel fibre-reinforced concrete enables its utilization in composite steel-concrete structures. This work is focused on development of mechanical ... -
TEMPERATURE DISTRIBUTION IN THE COATBACT OF A PARTIALLY FIRE-PROTECTED MEMBER
Autor: Dobrovolný P.; Šejna J.; Wald F.
(University of Ljubljana, Faculty of Civil and Geod, 2021)Whenever fire unprotected steel members are attached to a fire-protected steel member and penetrate its passive fire protection, additional heat will be conducted to this member during a fire. This can result in a local ... -
To fire resistance of the steel and fibre-reinforced concrete circular hollow section column
Autor: Tretyakov A.; Tkalenko I.; Wald F.; Novák J.; Štefan R.; Kohoutková A.
(CRC Press/Balkema, 2017)Technology of production and transport of the steel fibre-reinforced concrete enables its utilization in composite steel-concrete structures. This research is focused on development of mechanical behaviour and design model ... -
To shear failure of steel and fibre-reinforced concrete circular hollow section composite column at elevated temperature
Autor: Arha T.; Křístek V.; Tretyakov A.; Blesák L.; Tkalenko I.; Wald F.; Štefan R.; Novák J.; Kohoutková A.
(Editorial Universitat Politècnica de València, 2018)This study predicts the shear strength of steel fibre reinforced concrete (SFRC) members at elevated temperature using numerical modelling. The authors derived the stress-strain relation in the pure shear mode at ambient ...
