EXPERIMENTAL STUDY OF ENERGY EFFICIENT THREE-LAYER REINFORCED CONCRETE WALL PANELS WITH FLEXIBLE LAYER CONNECTIONS

The connections between the panels are the most critical structural elements that determine the performance of the building. The article highlights the results of testing the strength of flexible ties of three-layer reinforced concrete exterior wall panels with expanded polystyrene insulation by the static method. Studies were carried out on the mutual shift of the outer layer of the panel in relation to the inner one when testing concrete layers in accordance with the control values. The results of the experimental studies have shown that the use of metal flexible connections to connect the outer and inner layers of three-layer wall panels with insulation provides strength and reliability of structures under static loads. The tested three-layer reinforced concrete exterior wall panels, designed for large-panel housing construction of the 105 series, fully comply with safety requirements during operation.
