TRANSFORMATION ELEMENT BETWEEN THE DEPENDENCE OF THE FRAC- TURE MECHANICS AND THE EQUATIONS OF THE REINFORCED CONCRETE THEORY IN THE CONDITIONS OF A COMPLEX RESISTANCE

Abstract

The hypothesis of fracture mechanics is developed in the article and a universal short dual-console element is designed for reinforced concrete structures of buildings and structures. The proposed dual-console element is applicable to the evaluation of reinforced concrete structures resistance under conditions of various force and deformation effects, including torsion with bending. Simplified dependences are constructed for the energy functional and the specifics and features of the construction of a dual-console fracture mechanics element in the zones adjacent to the spatial cracks are considered taking into account the discontinuity effect. The dual-console element is the connecting link and serves as a transformational element between the dependencies of fracture mechanics and the equations of reinforced concrete theory.
