摘要

The construction of experimental specimens and the results of the study of concrete deformations of linear and cross beams in the biaxial compression zone using an optical-digital system (ODS) are presented. The features of the change in the deformed state of the compressed concrete of the cross beams’ top surface in the zone of their intersection at all loading stages until the fracture of the upper layer of concrete are revealed using ODS. The deformation characteristics of the concrete of these beams under biaxial compression are less than those of the same linear beams tested separately under uniaxial compression.
