Title of the articleDevelopment of a method for predicting the durability of a three-layer roofing structure
Abstract.Problem statement. The aim of the research is the development of the method for predicting the durability of three-layer walling using roofing sandwich panels with expanded polystyrene filler as an example. Results. The main results of the study are: - The analysis of regulatory prerequisites for the prediction of the durability of building envelopes; - The study of existing methods for predicting the durability of building envelopes; - The development of the finite-element model of the roofing sandwich panel, which allows us to study the mechanism of loss of performance, of the materials being studied, to determine the main factors affecting their operational life; - Modeling the operation of roofing sandwich panels under load using the PC «Lira»; - The study of the patterns of destruction and deformation of roofing sandwich panels with a filler of expanded polystyrene when varying specified constant stresses and temperatures. Conclusions. The significance of the results for the construction industry is to improve the methods of forecasting the durability of enclosing structures, allowing to determine the service life of building materials and products.
Keywords.sandwich-panels, foamed polystyrene, sheet assemble designs, prefabricated panels, block-farms, durability, prognostication, temperature and time analogy.
