In this article, the stress state of a wooden beam reinforced with polymer composite reinforcement made of carbon tape of various lengths is investigated. The minimum required length of a carbon fabric-based reinforcing tape is determined in the most loaded lower stretched zone of a single-span solid-wood beam.

Keywords: solid-wood beam, polymer composite construction, carbon fabric tape, physical and mechanical characteristics of the composite, design load, place of breakage of the reinforcing tape, stress state of the beam, stress concentration zone
