While calculating reinforced concrete constructions the relationship momentum - curvature M(κ) has significant importance. In exploitation conditions reinforced concrete construction is subjected to increasing loading and unloading. In bent moments, performing even a few cycles of static loading and unloading causes increase in temporary deflection. Building a unified model of relationship M(κ) describing the whole range from the elastic state to the full plasticisation, allowing for variable reversible loads (hysteresis loop) requires further investigations. Degradation of cross section stiffness is the result of damage process and plasticisation. Unified description of processes taking place in reinforced concrete beam cross section can be obtained with the use of elastic work probability, plastic work probability and damage relating cross section stiffness.
