Abstract. The authors consider the technique of experimental and theoretical evaluation of decreasing life resource of reinforced concrete structures of residential buildings under permanent industrial large-scale explosions of the capacity of 500 to 700 tons in the quarry of PGZK in Kryvyi Rih, Ukraine. On the basis of numerous experimental data and results of mathematical modeling, a probabilistic forecast model has been obtained for deterioration of the technical condition of reinforced concrete structures of the Children and Youth Creativity Center "Mriya" located in the Ingulets district. Calculations of the risks of destruction of the load-bearing elements of the building for its vulnerable areas have made it possible to correct the operation period of the building (by decreasing it by ~ 30 years in 2012 as compared with the normative one).
Keywords: living resourse, explosion, risk, destruction, experiment, calculation.
