A MODEL FOR ASSESSING THE PARAMETERS OF THE OPERATIONAL SUITABILITY OF SPECIAL STRUCTURES IN CONDITIONS OF DEGRADATION AND RISK OF EMERGENCY SITUATIONS

Within the framework of this work, a model for assessing the parameters of the operational suitability of load-bearing structures of special structures in conditions of degradation and risk of emergency situations is proposed. The developed model uses an integrated approach based on parametric identification of materials and load-bearing structures of special structures of the launch complex and the creation of similarity criteria for damaged and undamaged load-bearing structures, identification of critically important load-bearing structures after exposure to emergency loads and impacts. A physical model of parametric identification of special structures has been developed, taking into account the parameters of damage, strength and deformability of structures. Criteria for the similarity of load-bearing structures of special structures for various stages of operation are constructed.
