Investigation of the Stress–Strain State of Wooden Beams with Rational Reinforcement with Composite Materials

The preservation of retro structures in the monuments of wooden architecture is an important task. During long-term operation (100 years or more), retro wooden structures are exposed to atmospheric and environmental adverse environmental influences. The load-bearing capacity of retro wooden structures can be restored by modifying local destruction zones with polymer compositions. In the proposed technologies for restoring the load–bearing capacity, the peculiarities of changing the stress–strain state of wooden beam retroconstructions with locally destructive sections that have undergone modification have not been sufficiently investigated. Having studied the existing technologies of modification and reinforcement of retro structures, a new method of modification is proposed. The restoration of the bearing capacity of the elements of retro wooden structures with destructive damage to wood is assumed to be modified by the component composition of a polymer composition with a carbon filler under excessive pressure of pulsed action. The developed modification technology according to the results of the study is effective.
