The damage of a stone facing layer at the junction with reinforced concrete floors

Abstract

The article provides an analysis of the technical state of a stone facing layer of two-layer facade walls of monolithic buildings at the junction with reinforced concrete floors. The results of the numerical investigations of the stress-strain state of floor-by-floor supported multilayered walls with a facing layer at temperature influences are given. The analysis of the resistance of the facing layer of the wall to temperature effects, taking into account the deformation characteristics of mortar joints, was carried out. It was shown that the use of high-quality mortars in the facing layer increases the compressive stress on its contact with the slab.
