Investigation of the Resistance to Operational Impacts of Sets for Structural Glazing of Facades

The article presents the results of the tests carried out to determine the physical and mechanical properties of the sealant joint specimen in tension and shear before and after the onset of climatic influences, as well as a method for processing the results of such tests. The work carried out made it possible to establish the order of cycles of climatic influences in laboratory conditions on samples-seams, as well as to determine the main controlled parameters characterizing structural sealants – tensile strength and shear strength before and after a cycle of climatic influences. Comparison of the initial indicators with those after artificial climatic influences made it possible to determine the resistance of silicone sealants to a complex of climatic influences, depending on the change in one or more indicators of their properties (physical and mechanical, appearance, etc.). As a result of the work, a list of the main test methods was determined to confirm the stability of sets for structural glazing of facades and roofs using silicone sealants in glass-glass and glass-aluminum combinations to operational impacts in the climatic conditions of the Russian Federation, and a method for processing the results of such tests was proposed. The results of this scientific research can be taken into account when developing regulatory and technical documents responsible for quality control of structural sealants used in the creation of external translucent structures, and also allow determining the timing of major repairs and, consequently, the payback period for certain innovative solutions.
