Abstract
The stress-strain state of masonry walls made of large-format ceramic blocks with vertical tongue- and-groove dry joints is investigated. A numerical study of the masonry stress state of a wall fragment under a concentrated load is carried out on the wall model. The fragment of the wall was modeled by volumetric finite elements. It was found that under a concentrated load the deformed zone has the form of a triangle with a peak under the load and widening as the distance from the place of load application increases. An approximate method for determining the compressive stresses in the chain-link masonry elements under a concentrated load in the form of a distribution triangle has been proposed. The peculiarities of compressive stresses distribution in chain masonry walls made of large-format masonry stones under concentrated load have been established.
