The strength and deformability of the large-format porous ceramic blocks masonry under shear

Abstract

The article presents the results of experimental studies of shear strength, shear modulus and the limit value of the angle of shear deformations of masonry made of porous ceramic blocks with groove connection system of vertical joints. Studies of these parameters were carried out by the method of diagonal compression of masonry specimens, the vertical joints of which were made without filling and with filling with mortar. It is established that when filling vertical joints of masonry with a mortar on a mineral binding material, its shear strength and shear modulus significantly increase. It is indicated that it is necessary to take these factors into account when designing wall-stiffening diaphragms, multi-loaded load-bearing walls, floor-by-floor supported walls and partitions constructing using masonry from porous ceramic blocks.
