The features of the resistance of the support nodes of flexible reinforced concrete crossbars are considered taking into account the temperature effects. As the main area of work, a theoretical study of the influence of temperature effects on the strength and configuration of embedded metal parts and welds of the support nodes of prefabricated crossbars of various types is presented, which is an expression of the result achieved. The documents of the regulatory framework governing the design and construction activities in the Russian Federation, the existing constructive solutions of the support nodes, as well as the works of domestic and foreign scientists corresponding to the studies in this area are used. Research methods are structural and analytical analysis. Regulatory and scientific-methodological materials were studied, which made it possible to establish the parameters and factors affecting the constructive solution of the support nodes of flexible concrete elements. On this basis, proposals for improving the calculation and design solutions of support nodes are substantiated. Proposals have been developed for the calculation and design of support nodes taking into account temperature effects. It was revealed that the influence of temperature deformations significantly affects the operation of the support unit. The boundary ranges of temperatures and element sizes are determined at which the consideration of temperature effects is necessary. The features of the stress-strain state of the support node are clarified. Design recommendations are provided that provide strength and durability of the structure.
