Air-entrainment as an alternative to polypropylene fibers and its effect on the compressive strength of concrete at high temperatures
(IOP Publishing Ltd, 2019)
Although much research has been done in the area of the fire response of concrete in the past decades, only few studies are focused on the mechanical properties of air-entrained concrete at high temperatures. This paper ...
THE STEEL AND FIBRE-REINFORCED CONCRETE CIRCULAR HOLLOW SECTION COMPOSITE COLUMN EXPOSED TO FIRE
(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 ...
Flexural stiffness of the composite steel and fibre-reinforced concrete circular hollow section column
(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
(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 ...
Experimental Investigation of the Compressive Strength of Normal-strength Air-entrained Concrete at High Temperatures
(Elsevier Science, 2020)
Over the past decades, the mechanical properties of concrete during fire have been extensively investigated; however, not many studies were aimed at the properties of air-entrained concrete (AEC), and even fewer were aimed ...
To shear failure of steel and fibre-reinforced concrete circular hollow section composite column at elevated temperature
(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 ...
To fire resistance of the steel and fibre-reinforced concrete circular hollow section column
(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 ...
Provzdušnění betonu jako alternativa k polypropylenovým vláknům a jeho vliv na pevnost v tlaku běžného betonu vystaveného působení vysokých teplot
(BETON TKS, 2020)
Ačkoliv již bylo provedeno mnoho studií zabývajících se mechanickými vlastnostmi betonu
vystaveného působení vysokých teplot, pouze několik z nich se věnovalo betonu provzdušněnému. V tomto článku jsou prezentovány výsledky ...
