This article presents the results of experimental study of the strength of wood and concrete specimens under local buckling by a flat die under short-term loading action. At joint operation of a reinforced concrete slab and a timber beam in the connection there is buckling of timber and concrete elements, therefore it is necessary to know values of strength at these types of loading of timber and concrete. The strength values of timber, concrete on expanded clay aggregate, compression and buckling strength ratios of materials, as well as physical properties of materials according to the requirements of normative documents have been determined. The values of timber deformation were obtained and the graph of deformation dependence on stresses and graphs of deformation growth were plotted; the coefficient of soil stiffness was obtained to determine the strength for local crushing of materials
