3 CONCLUSIONS
Manifestation of rheological properties of concrete and soil
should be taken into account for the three moments of the
loading time: t=0; t→∞ and t= tcr. The results of the conducted
research show that the system gradually «adapts» to the
sustained load, which leads to increase in force in the first
loading period, and further – to their decrease (by 20-25%).
Consequently, a reserve for the load increase will appear in
structures under the sustained load.

Known buildings and structures damage, as well as the
machinery dysfunction has proved the importance of the issue
under consideration. The research conducted has confirmed the
possibility of applying the hereditary creep theory to determine
the vibrocreep settlement value. The reliability R2=0.97-0.99 of
data approximation with logarithmical function confirms the
accuracy of the technique developed.
