This paper presents the results of an experimental and numerical investigation of temperature developments in sandwich panels consisting of steel sheeting and polyisocyanurate (PIR) core. Fire experiments were carried out on individual PIR sandwich panels and PIR sandwich panels with joint. The fire test results were used to validate a temperature dependent thermal conductivity model for PIR, through numerical heat transfer modelling using the general finite element package ABAQUS. The fire test results indicate that the temperatures at the joint on the unexposed side of a sandwich panel is initially lower than that on the panel. However, at high temperatures, the ablation of PIR core creates large gaps up to 25 mm. Due to high radiation within the gap, the joint temperature becomes much higher than the panel temperature. The results of a numerical parametric study indicate that if the joint gap can be controlled to be no greater than 5 mm, the joint and the panel temperatures on the unexposed surface would be similar. Joint gaps of 10 mm or greater would result in joint temperatures much higher than panel temperatures and would reduce the sandwich panel system insulation performance of less than 60 min even though the panel may be able to reach much longer standard fire resistance rating. 相似文献

Building redevelopment – Solutions for roof and façade using lightweight steel construction . The research project ”Building redevelopment – Solutions for roof and façade using lightweight steel construction“ investigates possibilities to improve energetically existing roof and façade systems in lightweight steel and massive construction by using lightweight steel systems. As refurbishment systems steel sandwich panels as well as modular lightweight steel constructions, consisting for example of steel supporting profiles, thermal insulation and steel sheet profiles, will be applied. Besides hygrothermal‐building‐physical studies also static‐mechanical reviews for the energetically optimized building systems will be conducted. The present paper shows selected results that have been developed within the project. On the one hand, the energetic quality of existing façades in lightweight steel construction is shown, and savings potentials due to heat transmission, which are opened up by the renovation of these façades, are clarified. On the other hand, some of the resulting building‐structural questions with regard to load‐bearing behaviour and loadings are discussed. 相似文献
