Purpose The purpose of the study was to investigate spalling phenomenon in ultra-high performance fibre reinforced concrete (UHPFRC) beams on exposure a standard fire curve (ISO 834) under sustained load. Design/methodology/approach variables this were steel dosage, polypropylene (PP) fibres and loading levels. research investigated seven – three which contained with 2 vol.%, another had 4 vol.% dosage seventh beam combination (2 vol.%) PP (4 kg/m 3 ). tested for 1 h levels (20, 40 60 per...
Ultra‐high‐performance fiber‐reinforced concrete (UHPFRC) is a relatively new construction material. In comparison with conventional high‐strength concrete, UHPFRC does not usually contain coarse aggregates larger than 6–7 mm in size. This paper presents the outcomes of an experimental study beams subjected to four‐point loading. The effect two parameters was studied, namely, fiber content and temperature curing water. Eight were tested, comprising six reinforced rebars without rebars. Three...
This paper describes an experimental study at elevated temperatures on the behaviour of full-scale composite floor unprotected and protected cellular steel beams with intumescent coating having different size openings shape. All were designed for a full shear connections between beam concrete flange using headed studs in order to fail by web-post buckling. In fire, temperature distribution across member is non-uniform, since web bottom have thin cross-sections greater exposed perimeter than...

Most of the research on fiber reinforced polymer (FRP) bar structures employed glass FRP (GFRP) bars. The results tests, which were conducted carbon (CFRP) concrete beams, are reported in this article. beams with conventional steel rods tested as control specimens. Nearly equal crack spacing and number cracks noted both types at all stages loading. bond characteristics CFRP bars found to be satisfactory. ACI code equation over-estimated stiffness a result theoretical deflection, predicted by...
This paper presents the fire resistance behaviour of partially encased in concrete ultra shallow floor beams (USFB) using numerical analysis method based on material specifications EN1994-1-2. Investigating USFBs under elevated temperatures is crucial determining their and evaluating overall performance contemporary construction. Even though manufacturing company provides resistances for EC4-1-2 procedures, response to temperature effects remains up date neither well documented nor clearly...
The establishment of the fire resistance concrete structures reinforced with fibre-reinforced polymer (FRP) bars is a prerequisite to widespread applications fibrous rods in buildings. This paper presents results an experimental study, which was conducted investigate performance beams carbon FRP (CFRP) bars. were designed over-reinforced and subjected standard heating curve floor furnace. Full service load applied half hour before start test kept constant for duration test. A non-uniform...
This paper describes a full-scale fire test performed recently on composite floor for analysing the possibility tensile membrane action to develop when unprotected steel beams in central part of are made cellular beams. The natural was created by wood crib load 700 MJ/m 2 and 9 m × 15 survived fire, which peaked at 1000°C lasted about 90 min. Blind predictions air temperature development software ‘Ozone' structural behaviour ‘Safir', proved quite satisfactory, also described.

The establishment of fire resistance the fiber-reinforced polymer (FRP) bar-reinforced concrete (RC) is a prerequisite to widespread applications these bars. use FRP bars in residential and commercial buildings could result their increased applications. This article presents an experimental study on performance carbon (CFRP) hybrid (steel—CFRP) RC beams at elevated temperatures. were tested floor furnace carried load 40% ambient capacity. Temperature rise compression was found insignificant...
