Review article

Preservation of the architectural heritage of St. Petersburg requires improving the technology of repair and restoration works of attic roofs, in particular, the main wooden load-bearing elements of the roof. The authors have not only considered constructive solutions, but also proposed a technological sequence of works, giving a preliminary assessment of the wear of the rafters affected by the fungus. In addition to traditional methods of reinforcing rafters with truss ties, a research direction is proposed for the use of composite materials for the manufacture of reinforcing truss ties.
