THE STRENGTH OF CONCRETE IN TENSION ZONE BETWEEN THE CRACKS OF COMPOSITE REINFORCED CONCRETE STRUCTURES CONSIDERING NEW EFFECTS
The work presents a methodology based on traditional preconditions of the theory of reinforced concrete and propositions of fracture mechanics, which allows to specify the basic parameters of the strength of concrete. There are new obtained dependences for estimation of the strength of concrete in tension area between cracks for composite eccentric-compressed reinforced concrete structures, taking into account the effect of discontinuity and conventional displacements. In this case there are several levels of cracks appearing up to the moment of failure.
