Wood construction codes

The wood construction codes supported by Verisk Synergy Studio.

Note: Verisk Synergy Studio applies non-engineered building damage distributions to the following construction classes: 101, 102, 103, 104, 111, 112, 113, 114, 115, 173, 174, 178, 179, 261. This action occurs regardless of occupancy class, including the industrial facility (400-series) occupancy classes. This note applies to several models.

For information about supported codes and limitations for specific models, refer to the model documentation that is available on the Client Portal (login required).

Construction code Category Description
101 Wood Frame (Modern) Wood frame (modern) structures tend to be mostly low rise (one to three stories, occasionally four). Stud walls are typically constructed of 2x4 or 2x6 inch wood members vertically set 16 or 24 inches apart. These walls are braced by plywood or by diagonals made of wood or steel. Many detached single and low-rise multiple family residences in the United States are of stud wall wood frame construction.
102 Light Wood Frame Light wood frame structures are typically not built in the United States but would be found in other countries, such as Japan. In Hawaii, this classification would include single wall (studless) construction framed with light timber trusses.
103 Masonry Veneer A wood-framed structure faced with a single width of non-load-bearing concrete, stone, or clay brick attached to the stud wall.
104 Heavy Timber Heavy timber structures typically have masonry walls with heavy wood column supports, and floor and roof decks are 2-3 inch tongue-and-groove planks.
107 Lightweight Cladding Non-structural cladding and linings (e.g., fiber cement, plywood) used in lightweight construction that uses timber or light gauge steel framing as the structural support system.
108 Hale Construction Indigenous Hawaiian construction.
