The analysis of the stress-strain state occurring in the walls during the shrinkage of masonry of cellular concrete blocks mounted on the reinforced concrete monolithic floor is made. A numerical model of the frame stone filling is developed. It is shown that under the influence of shrinkage the value of the main tensile stresses in the stone masonry nonlinearly depends on the stiffness of the wall connection nodes with the vertical elements of the frame. When fixing the walls with rigid ties, in the masonry there are bursts of stresses in the places of installation of binding elements. The expediency of setting the links, ensuring the freedom of deformations of masonry in the plane of walls, but preventing its displacement from the plane of the frame is substantiated. Recommendations on reinforcement of window-sill and above the opening belts of masonry with steel or composite meshes placed in horizontal mortar joints of masonry are given.
