Influence of heat-conducting elements on temperature amplitude of inner surface of frame-supporting buildings

The paper considers the heat stability of enclosing structures of frame-supporting buildings. These buildings are characterized by a significant heterogeneity of enclosing structures. The supporting structures have a large number of uprights, beams, lintels, connectors, and heat-conducting elements such as building corners, balconies, window and door jambs, and plinth nodes.

Two typical junctions are considered for a frame-supporting building with light gauge steel framing and wooden frames. The Simulation module of the SolidWorks software is used to analyze the obtained minimum and maximum temperature on the inner surface. The diagram of the temperature distribution is suggested for two design solutions, i.e., the outer corner and floor junction, and the light gauge steel framing and wooden frame-supporting structure. It is found that near the heat-conducting elements, the maximum allowable value is exceed by 5 and 3 times for the light gauge steel and wooden framing respectively, which does not meet the standard requirements. The temperature fluctuations are observed in the junction between the floor and wall. Thus, for the light gauge steel framing, the temperature fluctuations occur at a distance of ~200 mm in the room, while in wooden-frame building, this distance is ~100 mm.
