Fire-Resistant Structures for Tunnels Using Light Concrete II

The subject of the article is to inform the experts about results of a set of fire resistance tests of light concretes designed for traffic and tunnel structures. In addition to commonly used recipe C 30/37 FX4, corresponding version of light concrete class LC 35/38/XF 4 was tested. One of the goals of the tests was verification of behaviour of “road” (XF4) concretes under the most demanding conditions of fire, especially in road tunnels. In addition to standard curve, the hydrocarbon and Eureka curves were used for the fire tests. The loading curves differ from normally used standard curve especially in the temperature rise speed (temperatures over 1,000°C are reached within a couple of minutes). In this case, real concrete moisture and possibility to remove water steams from a component are substantially important for the fire safety (integrity).

<p>Sandwich panel is the material that is easy and quickly to install. Basing on a great experience in the area of determination of the fire resistance class of construction building elements the authors describe the properties and behavior of building elements made of the sandwich panels exposed to fire. The article presents the results of fire resistance tests carried out in accordance with EN 1364-1 non-bearing walls made of sandwich panels with use of different cores.</p>The following parameters were analyzed: temperature rise on unexposed side (I – thermal insulation), integrity (E) depending on the orientations and on the width of the sandwich panels, deflection depending on the thickness of the boards. Conclusions were made on the base of the analysis from fire resistance tests.

The article presents the results of the study on the temperature distribution in fiberglass reinforced concrete beams produced by the KomAR in accordance with TU 2296-001-24488682-2014, on the basis of fire tests conducted in the test laboratory and test center for fire safety at the FGBU VNIIPO of EMERCOM of Russia. The value of the coefficient of working conditions of fiberglass rebar γ st is determined by analogy with SP 27.13330.2017 «Concrete and reinforced concrete structures designed to work in conditions of exposure to elevated and high temperatures», depending on the temperature.
