ICC-ES AC306
Full Name
ICC-ES AC306 – Acceptance Criteria for Pin-connected Open-web Trusses with Wood Chords and Tubular or Angular Steel Webs
Scope
ICC-ES AC306 is a set of acceptance criteria that covers the design, fabrication, and quality control of pin-connected open-web trusses with wood chords and tubular or angular steel webs. These trusses are commonly used in residential and light commercial construction for roof and floor support.
The scope of AC306 includes:
- Materials: it specifies the requirements for the wood chords, steel webs, and connection pins, including allowable species, grades, and dimensions.
- Design: it outlines the design methodology and load combinations to be considered, as well as the requirements for the truss configuration, member sizes, and connection details.
- Fabrication: it addresses the fabrication process, including welding, cutting, and assembly, to ensure the trusses are manufactured to the specified tolerances.
- Quality control: it establishes a quality control program to ensure that the trusses consistently meet the requirements of the acceptance criteria, including inspections and testing.
The AC306 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their trusses comply with the applicable building codes and standards.
