Abstract

The publication examines the generalization of results of experimental and theoretical studies of concrete under static and single-shot dynamic loading under conditions of single-axial, two-axis, three-axis stress states with the presence of tensile stresses. Dependences for determining concrete strength, concrete stress-strain modulus, concrete ultimate strains. Research results extend the idea of concrete behaviour at various types of force action and can be used in the calculation of structures for special combination of loads, taking into account the actual concrete properties.
