In the paper, the researchers have estimated the influence of pre-stressing of reinforced concrete
elements upon the dynamic loading parameters in the event of beyond-design actions.
In particular, the case of reinforcement of a crossbar, if considered absent of any pre-stressing,
is considered in the paper. The authors have proven that the presence of brittle fracture elements
leads to decay in time-driven vibrations of rods within the statically indeterminate structural system.
The findings have been made on the basis of the magnitude of specific efforts (the bending moment)
and the corresponding strain. Besides, the authors have formulated the condition of permanence of
the total per-unit energy of structural elements. The influence of the above-mentioned parameters
on the design safety of a system is identified.
