The article describes a method for checking the ultimate limit state of multilayer walls supported floor-by-floor with a facing layer under wind loads. We have conducted an analysis of the resistance of the multilayer wall structure to wind effects, taking into account the strength and deformation characteristics of the cladding and core layers, and the conditions for securing the masonry wall to the frame structure. It was shown that the use of a base layer for multilayer walls with brick veneer masonry with a low modulus of deformation, and the lack of consolidation of the base layer to the support increase the overlap of bending moments in the facing layer. It was found that the onset of the ultimate limit state of multilayer walls which base layer is made of 300 mm-thick porous concrete blocks is determined by the resistance of the masonry cladding layer to wind loads. Proposals for the design of multilayer walls with supported floor-by-floor with a facing layer of brick were formulated.
