Today in Ukraine, there is no single legalized, generally accepted
methodology (at the level of a Ukrainian building standard) for dynamic certification of
buildings and structures. A unified approach is proposed as such a technique. It includes
four components: visual inspection of buildings; experimental studies of the dynamic response
of buildings or structures to explosive effects; mathematical modeling of the
stress-strain state of the object under study; synthesis of the results of visual inspection;
experimental studies and numerical simulation in order to generalize them systematically.
As an approbation, the deterioration of the resource of reinforced concrete structures
of residential buildings under the conditions of constant mass industrial explosions
with a capacity of 500 to 700 tons in the quarry of Southern GZK (Mining and
Processing Plant) in the city of Kryvyi Rih, Ukraine, has been studied. Based on the
processing of numerous experimental data and the results of mathematical modeling,
a probabilistic model for predicting the deterioration of the technical condition of reinforced
concrete structures of the Center for Children and Youth Creativity
“Mriya” has been obtained. Calculations of the risks of destruction of the building’s
load-bearing elements for its vulnerable areas made it possible to clarify its service
life. It decreased by 30 years compared to the standard in 2012.
