Abstract

In this paper, the authors study the stress-strain state of composite jumpers made of aerated concrete blocks with steel reinforcement rods and external composite reinforcement when working in bending. Rod reinforcement of jumpers is carried out by inserting steel reinforcing bars into the body of aerated concrete in the longitudinal and transverse directions. Composite reinforcement is performed with carbon fiber tapes in the stretched edge of the element over the entire width, as well as parts of tapes on the flange sides of the aerated concrete block at the vertical seam or in the center of the element. The test results are assessed by comparing the strength of the normal section and the deformability of aerated concrete bending jumpers, the effectiveness of gluing carbon fiber tapes and aerated concrete, and the optimal use of various types of reinforcement. It has been established that external composite reinforcement at a load of up to 60% of the breaking load reduces the deformability of aerated concrete bending elements due to an increase in flexural rigidity, and at a load of more than 60% due to a change in the design scheme. Jumpers with rod reinforcement have a brittle nature of destruction, while those with external composite reinforcement fail plastically. In general, the load-bearing capacity of composite aerated concrete jumpers reinforced with external composite reinforcement is sufficient to withstand operational loads
