ICC-ES AC343
Full Name
ICC-ES AC343 – Acceptance Criteria for Composite Open Web Steel Joists Supporting Concrete Decks
Scope
ICC-ES AC343 establishes the acceptance criteria for evaluating composite, open-web steel joists designed to support cast-in-place structural concrete decks in building construction.
The scope of AC343 includes:
- Materials: specifications for the materials used in the joists, including steel properties and welding requirements, to ensure structural integrity and durability.
- Design and analysis: guidelines for the design and analysis of composite joist systems, considering factors such as load distribution, deflection, and vibration.
- Testing: standardized test methods for evaluating the strength and stiffness of composite joists under various loading conditions, including bending, shear, and combined loading.
- Construction: requirements for the proper installation and connection of composite joists to supporting members and the concrete deck.
- Fire resistance: evaluation of the fire resistance rating of composite joist systems to meet building code requirements.
By adhering to AC343, manufacturers can ensure that their composite open-web steel joists meet the necessary standards for safety and performance in supporting concrete decks.
