Abstract: The article considers the issue of heat resistance of external structures of residential buildings made according to the frame-panel scheme. One of the features of frame-panel buildings is a high level of heterogeneity of external protective structures. The boards have a large number of racks, crossbars, jumpers and connecting elements. At the same time, we should not forget about linear heat-conducting inclusions caused by the shape of the building – external and internal corners of the building, balconies, window and door slopes and basements. Two characteristic junctions for buildings made by the frame-panel method were considered, with two types of frames: LSTK profiles and wooden solid beams. As a result of the analysis of the obtained values, in the Simulation module of the SolidWorks software package, minimum and maximum values of temperatures on the inner surface in time, a scheme of distribution of oscillation amplitudes was constructed for two calculation schemes: the outer corner of the building and the junction of the floor and the wall with LSTK and a wooden frame of the shield panel. It is established that in the zone of heat-conducting inclusions the construction exceeds the maximum allowable normative value by 5 and 3 times for LSTK and wooden profiles, respectively, which does not meet the regulatory requirements.

Keywords: heat resistance, non-stationary mode, temperature field, redistribution, amplitude, method.
