description: The work is devoted to the study of the stress-strain characteristics and bearing capacity of lattice concrete beams, reinforced with composite reinforcement, by means of an experiment and the calculation of the considered structures by manual and numerical methods of calculation. Research includes the following tasks: 1. Analyze the properties of composite reinforcement and compare the characteristics of composite and steel reinforcement; 2. Experimentally and theoretically, to investigate the parameters of the stress-strain state of prototypes; 3. Perform the calculation of the considered experimental structures for the st and 2nd groups of limiting states; 4. Process and analyze the results of the experimental study. In the course of the work, the main physical and mechanical characteristics of composite reinforcement, its current state in the construction market were analyzed, a comparison of composite and steel reinforcement was made. The calculation of the investigated structures was carried out for two groups of limiting states manually and using the SCAD Office 21.1 software package. Experimental studies on testing lattice concrete beams using composite reinforcement were carried out in the research laboratory of building structures and materials "Polytech-SKiM-Test". As a result of the tests, such characteristics as breaking load, deflections, relative deformations and stresses arising in beams at different loading stages were obtained. As a result of the work, the promise of composite reinforcement was proved, but it was concluded that it is inexpedient to completely replace steel reinforcement with composite reinforcement in bent structures in view of the low modulus of elasticity.
