The high temperature fire resistance of vanadium is not well documented, so its properties are usually approximated to the same as conventional structural steels. The goal of this study is to determine the properties that influence the fire resistance of structural steel, thermal conductivity, specific heat and thermal elongation. Thermal conductivity and specific heat were both determined through a transient plane source (TPS) method. Vanadium and A36 steel were both ...
The structural integrity of steel members is jeopardized when fire insulation is partially lost. This paper examined the thermal and mechanical properties of fire insulation under elevated temperatures to further understand thermal gradients and develop preventative safety measures. A thermal analyzer measured the thermal conductivity of the insulation material using the transient plane source (TPS) method. Results show that thermal conductivity increases with temperature because the spray-applied fire resistance materials ...
Gypsum board is a building material that shrinks and cracks at high temperatures, which compromises the structural integrity of buildings during fires. Researchers in this study set out to determine the behavior of gypsum board when exposed to real fire conditions. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the gypsum board samples at and above room temperature using the transient plane source (TPS) technique. Results showed that ...
The mechanical and thermal properties of structural steel were examined at ambient and high temperature to evaluate the predictive models of current design codes. Tensile coupon tests were performed to evaluate the mechanical properties. Thermal elongation was determined using a high-temperature extensometer, while the thermal conductivity and specific heat capacity were determined using the transient plane source technique. Specifically, the slab method was used. The determined mechanical properties were used ...
Using a combination of transient plane source (TPS) technique and slug calorimetry, 4 commercially available fire resistive materials (FRMs) are studied from room temperature to 1000°C. The materials studied in this report are two gypsum-based and two calcium-silicate based materials. These materials are heterogeneous and thus when heated to elevated temperatures, the microstructure of the materials may be compromised and various reactions and phase changes may take place over the course ...
