Sealed Truss Placement Diagrams - Texas

It can be often misunderstood whether a Truss Design Engineer has the responsibility to seal a Truss Placement Diagram (TPD). The purpose of this Research Report is to provide the relevant code sections from the latest editions of the International Building Code (IBC) for thorough analysis and interpretation, as they relate to the state of Texas. 

What the Code Says: Truss Placement Diagrams

Truss placement diagrams (TPDs) may be one of the more misunderstood documents in our industry. 

Sealed Truss Placement Diagrams - California

It can be often misunderstood whether Truss Designers have the responsibility to seal a Truss Placement Diagram (TPD). The purpose of this Research Report is to provide the relevant code sections from the International Building Code (IBC) and the California Building Code for a thorough analysis and interpretation. 

Truss Repair

The repair and modification of metal plate connected wood trusses can be a very complicated subject, because each situation must be analyzed individually. This Research Report will give an overview of the fundamental principles behind truss repair that inform the truss designer’s approach in all truss scenarios.

Truss Industry Standard of Care Issues: Part 4

Truss industry standard of care items are contained throughout ANSI/TPI 1,* The National Standard for Metal Plate Connected Wood Truss Construction. The focus of this article is ANSI/TPI 1 Chapter 2, Section 2.3.5.1 and companion Section 2.4.5.1, which require a truss designer to prepare truss design drawings (TDD) based on design criteria and requirements set forth in the construction documents. The truss industry should expect to get this information from the building designer (BD), which may include the building owner, contractor or a registered design professional (RDP). Particularly when there is an RDP for the building, the design community expects the truss industry to design components that conform to the truss framing plan and specified design parameters within the construction documents, unless instructed otherwise in writing.

 

Truss Industry Standard of Care Issues: Part 3

The first two Standard of Care articles discussed deferred submittals and truss-to-truss connections. This article explores truss minimum required bearing width issues from the perspective of the design community.

Truss Industry Standard of Care Issues: Part 2

The purpose of this article series is to identify truss-related structural issues sometimes missed due to the day-in and day-out demands of truss design/production and the fragmented building design review and approval process. This series will explore issues in the building market that are not normally focused upon, and provide recommended best-practice guidance.
