Introduction . The fire resistance limits of load-bearing and enclosing structures can be identified using the method heat-and-mass transfer calculation in case fire. multifactorial nature nonlinearity problem makes application this complicated. If necessary, temperature regime, demonstrating conditions real fire, applied. In work, actual metal a thermal power station are calculated.Goals objec...

In this article the research of fire resistance limits structures for industrial facilities has been carried out. It is known that building are determined by experimental and computational methods. The to solve problem was based on temperature regime real conditions. purpose study assess production calculating heat mass transfer, taking into account To achieve goal we need following: 1. Investi...

Composite materials, such as glass fibre reinforced polymers (GFRPs), possess the advantages of high strength and stiffness, low density, as well as manufacturing flexibility; therefore, their potential in replacing conventional materials (such as concrete, aluminium and steel) in building construction has become attractive. One of the major issues that hinder the extensive use of composite str...

The paper presents results from three large scale experiments on seven reinforced concrete panels obtained during an extensive experimental program. This was aimed at possible application of cement reduced (fly ash replaced) concrete in the production of precast segmental linings for tunnels created by a tunnel boring machine (TBM). In particular, this paper is focused on the comparison of fire...

The use of fiber reinforced polymer (FRP) bars in reinforced concrete members enhances corrosion resistance when compared to traditional steel reinforcing bars. Although there is ample research available on the behavior of FRP bars and concrete members reinforced with FRP bars under elevated temperatures (due to fire), there is little published information available on their post-fire residual ...

This paper focuses on current trends in the flame retardancy of epoxy-based thermosets. This review examines the incorporation of additives in these polymers, including synergism effects. Reactive flame-retardants-which are incorporated in the polymer backbone-are reported and the use of fire-retardant epoxy coatings for materials protection is also considered.

Induced defense is a common plant strategy in response to herbivory. Although abiotic damage, such as physical wounding, pruning, and heating, can induce plant defense, the effect of such damage by large-scale abiotic disturbances on induced defenses has not been explored and could have important consequences for plant survival facing future biotic disturbances. Historically, low-severity wildf...
