A long-term strength materials under an axially loading of constructive elements is considered and the estimates of this strength are reduced. The proposed approach is connected with the notion so-called energy of entirety [1]. It is notable that this value can be used instead of known Reiner’s invariant [2]. A material (concrete, steel, graph) is considered as a union of its links with statistical disturbed strengths [3]. This conception allows to modify Boltzmann’s principle superposition of fraction creep deformations [4] and in addition, implies the identity of non-linear stresses function for the instantaneous and retarding deformations. The degeneration of long-term strength because of vibrational influence take into account and the strengthening of the materials in the course of their formation is considered.
