The object of research is multi-span wooden beams reinforced with fiberglass rods in a stretched zone. The purpose of the study is to study the stress-strain state of multi-span wooden beams reinforced with fiberglass reinforcement. Studies of single-span wooden structures with fiberglass reinforcement have shown positive results, including under prolonged loads and with the use of pre-stress. At the same time, multi-span wood-glued beams using fiberglass rods as a reinforcing material are an experimental design and today their work is poorly studied, which makes this task relevant.
The research was carried out on 3 variants of beam structures, two of which are wood-composite, one – solid wood, given as a standard. Taking into account the scheme of operation, composite rods are located both at the bottom of the section – in spans, and at the top – on supports. Depending on the coefficient of reinforcement, the strength of beams reinforced with fiberglass rods in stretched zones increases by 32–37%, and the deformability decreases in the range of 15–19% compared to standard wooden beams. Based on the results obtained, we can conclude that the considered method of strengthening wooden beams is appropriate and effective.
