The goal is achieved by developing suggestions for creation of several options for implementation of functional units, synthesis of subsystems of a bridge structure equipped with the SOCSC, for various options of implementation of functional components and selection of the final one from them under the condition of ensuring the permissible stresses in the SOCSC, determined from a generalized model of stress-strain state of the SOCSC, which is developed considering their interaction with all functional units and takes into account their parameters, their changes during operation and changes in mechanical characteristics of the SOCSC during operation and over time. popup.nrat_date 2024-12-09 Close
