When looking through the Lvl Beam Span Table, there are several important factors to consider. ![]() Ask your builder if he is following the plans or ask to look at the plans to confirm that this was part of the initial design. Span tables allow users to choose an appropriate size and stress grade to achieve spanning needs. Many permit offices will require engineering if there are no span tables available for the specific application. If a lumber rafter of similar or less size can work here, then the LVL definitely can as well. Effective column length is equal to actual column length. Using your numbers, the rafter span you are looking for in the code table 10'-1 11/16" Table assumes that the column is braced at column ends only. The Kerto manual includes four chapters of the most common connector types (Nailed, Screwed, Dowelled and Bolted. The manual also offers a proper info package about Kerto products and their applications. An LVL is manufactured without the natural defects that can be found in lumber, therefore an LVL can deliver better performance than a similar sized piece of lumber. Kerto manual is a tool for the structural designer which helps in design of wooden structures according to Eurocode 5. ![]()
