Chapter Summaries

Section 14.1 Framing Systems & Structural Design
Balloon-frame and platform-frame construction make use of many individual pieces of wood. Platform-frame construction is the most common system used to build houses. Other framing methods include post-and-beam, timber framing, and structural insulated panels. The design of wood framing is based on laboratory tests of wood samples. The wood is given a rating based on its resistance to stresses. Test results are summarized in tables of design values.

Section 14.2 Nails & Connectors
Choosing the correct nail is very important when assembling wood framing. Metal framing connectors improve the strength of joints. Types include joist hangers, I-joist hangers, and ties and straps. Always use the type and size of nail recommended for the installation of framing connectors.
