Heavy joist span tables


Where can I find joist span tables for heavy cut timber joists. Like 4x14 joists. It is for a large log home that is 40 x 40. It has a log girder across the middle giving 20' spans. An engineer told me 4x14 that are 32" oc. It has 2x6 T&G decking on top. I can find any tables to check myself.

Heavy joist span tables


I am not aware of tables for large format beams. I use a spreadsheet I developed based on fundamental mechanical properties, which I use frequently for a wide range of lumber sizes. Perhaps you should discuss the matter with your engineer, when you get into large size wood beams there are certain considerations such as proper connections that are outside the realm of standard code, and require careful design.
