Influence of the heat insulation layer on the thermally stressed condition of the facade wall

Abstract The temperature-stress state of the concrete facade wall with a window opening, which is external enclosing structure room steel heating device, was investigated by method numerical modeling. Estimated studies were performed for winter period when system building functioning. According to results solving equations thermal stress and equation conductivity, temperature distribution over volume normal tangential stresses determined. Areas where these are maximum identified. research cases both, absence presence heat-insulating layer on outer surface wall. From comparison obtained two options, it follows that insulation coating not only helps reduce dissipative heat loss through wall, but also reduces absolute values in arising resulting from deformations. In some cases, sign changes stretching (wall without insulation) compressive insulation).
