ANSI/TPI 1-2022 has added a new person loading check in Section 6.2.2.5 to represent the occurrence of a person on the chord of a truss. This provision only applies to chords not sheathed with structural wood sheathing. The provision was introduced to enhance safety by ensuring that truss chords can support a worker during temporary conditions, such as access for maintenance or installation activities.
It is important for truss technicians and truss designers to understand this provision and the potential impact it may have on truss designs. In some instances, the provision may control the design of a truss chord resulting in larger member sizes, or smaller panel lengths than previously required.
