Experimental Studies of the Possibility of Estimating the Operating Resource of Composite Structures under their Power Loading and Industrial Building Structures

The article presents the results of experimental studies of the possibility of assessing the resource of various structures made of polymer composite materials (PCM) when applying power loads (uniaxial power static and cyclic) to them based on the analysis of the results of their non-destructive testing and industrial building objects using artificial neural networks (ANNs). It is shown that the error in assessing the service life of structures from PCMs when they are loaded with a uniaxial power load and cyclic load using the proposed method does not exceed 15 %, and for industrial construction objects, the dependence of the probability of a pre-emergency state on the operating time is formed. The data obtained allow timely repair work of structures or their decommissioning and prevent emergencies.
