Abstract: There are great amount of concrete and reinforced concrete structures under the action of shear forces. They are important and widely used elements of buildings and constructions, and differ from each other by the construction determination, dimensions, forms and the character of stress-strain state in the shear plane. The strength design method is expounded for concrete and reinforced concrete elements by means of variation method in the concrete plasticity theory that was developed in Poltava National Technical University. There is also experimental investigation of the following elements: Gvozdev and Mersh specimens, wall-beams and truncated concrete wedges that simulate work of concrete compressed zone above dangerous inclined crack as the most well-known from offered for the strain condition and failure load determination for considered types of elements. In addition wedges and Gvozdev specimens from higher strength concrete have been tested for applicability determination of given method to these elements. The results of the experimental research have confirmed the applicability of plasticity zones assumed in the theoretical solutions. The theoretical strength is well coordinated with the experimental one.
Key words: strength, shear action, variation method, truncated wedge, wall-beam, Gvozdev specimen.
