ICC-ES AC425
Full Name
ICC-ES AC425 – Acceptance Criteria for Cold-Formed Steel Structural Beams Acting Compositely with Cast-in-place Concrete Slabs
Scope
ICC-ES AC425 outlines the acceptance criteria for evaluating cold-formed steel structural beams acting compositely with cast-in-place concrete slabs. These composite assemblies are used in building construction to achieve improved structural performance.
The criteria cover various aspects of the composite beam performance, including:
- Structural capacity: evaluates the combined flexural and shear strength of the composite beam section.
- Connection strength: assesses the strength and behavior of the connections between the steel beams and the concrete slab.
- Ductility: ensures the composite beam has adequate ductility to deform plastically before failure.
- Durability: evaluates the long-term performance of the composite beam under sustained loads and environmental factors.
The purpose of AC425 is to provide a standardized framework for evaluating these composite assemblies, ensuring they meet the minimum requirements for safety and performance in building construction.
