The use of composites to strengthen wooden structures is currently a popular construction solution. Despite the popularity of the solution, there are still no normative regulations specifying the methods of estimating the load-bearing capacity of wooden elements reinforced with composites. It is possible to use numerical methods, but it is a relatively laborious method. Due to the lack of normative requirements, engineers designing composite beams must use the methods presented in the literature. The article presents an overview of the most popular analytical methods for estimating the load-bearing capacity of reinforced wooden elements.
