Temperature Effects on Polymer Structures of Canopies for Inversion Roofs of Multi-Storey Residential Buildings

The influence of temperature effects on the technical condition of cross-rod spatial structures of canopies for inversion roofs of multi-storey residential buildings made of polymer materials is considered on the example of tubular elements made of polyvinyl chloride (PVC). For modern multi-storey residential buildings, the current regulatory and technical documentation provides for operational (inversion) roofs, which can accommodate children’s sports grounds, cafes, bars, restaurants, parking lots, tanning salons, as well as gardens and architectural and landscape objects, helicopter platforms, etc. To protect visitors against atmospheric influences, canopies made of spatial core building structures (SCBS), which are operated in the open air, taking into account various climatic influences: high and low temperatures, corresponding humidity, precipitation, etc., are recommended. The elements of the core system are of the greatest interest for taking into account the temperature impact on the technical condition of the developed structure. The general solution of the problem of non-stationary heat transfer of a structure for calculating a two-dimensional temperature field is considered in a nonlinear formulation. The problem of thermal conductivity is considered under the assumption that there is a technical possibility for supplying a coolant inside the cylinder. As a result, there is a heat flow, with which it is possible to adjust the temperature between the outer and inner areas of the cylindrical elements for more efficient installation of the stress-strain state of the entire supporting structure as a whole.
