How to Read Truss Documentation

Wednesday, March 6 from 8:40–9:40 am


Truss design drawings (TDDs) and truss placement diagrams (TPDs) are an important part of the documentation used in the metal-plate-connected wood truss industry. Truss manufacturers use these documents to communicate important safety, installation, restraint and bracing, and design information to owners, building designers, contractors, framers, and building officials. Understanding the information in these documents is crucial for a properly installed truss system. This presentation reviews truss industry–specific terminology and information included in TDDs, TPDs, and truss repair drawings to provide a practical working knowledge of trusses and how to best specify, install, and inspect them.


Structural Self-Tapping Fasteners for Wood Construction

Thursday, March 7 from 10:30–11:30 am


Connections are a critical part of a building’s design, and the type of fastener used for the connections can have a significant impact on the cost of constructing a building. The number of structural self-tapping fasteners available in the market is increasing. These fasteners have many advantages over traditional nails, lag screws, and through-bolts. Understanding these fasteners and their uses can make the construction of a building more efficient. This presentation will cover the advantages of using these fasteners, their design properties, where to find design information, and how to specify the fasteners.
