NDS Catalog

What is NDS?

NDS stands for the National Design Specfication. They provide a compendium of reference design values for wood construction. These specifications are chosen alongside manufacturers with the best design value in mind. The dimensions chosen are mainly overseen and approved by the American Wood Council along with other wood specialised councils. These specifications also provide a standard for the usage of wood. The NDS specification for wood is widely used by many manufacturers, giving companies the ease of access to the material. This also provides the benefit of not having to re-iterate through different dimensions. We in particular look at the use of Sawn Lumber (nominal and standard dressed dimensions), Western and Southern structural glued laminated timber


Using SkyCiv with NDS


Here at SkyCiv, we have coupled the NDS specification together with our section builder, giving users the ease of access without the hassle of entering all the dimensions from the catalog. This helps users directly compare dimensions provided from the catalog. As the database is part of our section builder, users can also calculate sectional properties that are normally not given by the catalog itself. Being one of the few companies to have digitized this catalog, we have made it so that users only have to pick the type and size of wood they need. This eliminates the cumbersome element of using not only this catalog, but we have also done it for other catalogs like the AISI Steel catalog or the AISC catalog and more.
