    Abstract. A comparative analysis of assessment of reliability of the compression test results of ceramic whole brick and ceramic large-format stone with voidness over 40% has been made in accordance with normative documents. On the basis of the experiment results, the dependence of the compressive strength of ceramic stone on the direction of application of the load relative to its faces is shown. The calculated characteristics of the compressive strength of large-format ceramic stone at different directions of application of the load to the side and end faces have been obtained. On the concrete examples of tests of wall fragments made of ceramic hollow bricks and stones for the effect of horizontal load with the use of domestic and foreign testing methods it is shown that the standard methodology of tests for warping used for walls made of ceramic whole brick does not correspond to real one due to the stressed state of masonry under the impact of horizontal seismic force during the earthquake. When designing buildings constructed in seismic regions, on the basis of experimental studies, it is necessary to determine the permissible for seismic regions grades of large-format stone for compression depending on the direction of load application to it.
    Key words: ceramic large-format stone with voidness over 40%, warping, compression test methodology, experiment, seismic load.
