Wooden cellular slabs with rectangular perforations are commonly used by civil engineers in settings such as concert halls, nurseries, hotels, airports, etc., for noise elimination and heat retention. In this study, fire resistance of perforated wooden slabs was tested in order to attain a numerical approach using the finite element method, when predicting the performance and behavior of the perforated wooden slabs. Paying close attention to the thermal properties of ...
This report details a project undertaken in 2006 and 2007 to verify the fire rating of gypsum wall/steel stud assemblies. Samples were sent to six different fire testing laboratories and tested in 10 different furnaces. All of the laboratories returned ratings of 1-h for the samples. Researchers measured the thermal conductivity and specific heat of the gypsum wall samples at room temperature. Measurements were taken with both the paper in place and ...
This paper used the TPS to measure the thermal conductivity of several different spray applied fire resistive materials between a temperature of 20-1000°C. Mass loss and thermal strain were also investigated. These properties are crucial components of the material, and decide how effectively it will perform in the face of a fire. Temperature was found to have a significant impact on the thermal conductivity, mass loss and thermal strain. ...
An equation for determining the effective thermal conductivity of fire resistive materials using a slug calorimeter was developed, and effective thermal conductivities were measured during heating and cooling cycles of these materials. The obtained values were compared to those obtained through measurements using the hot wire, and transient plane source methods. It was determined that the obtained values were in good agreement with those measured using these two methods. The ...
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 ...
