Full Name

ICC-ES AC495 – Acceptance Criteria for Cold-formed Steel Structural Beams with Steel Angle Anchors Acting Compositely with Cast-in-place Concrete Slabs

Scope

ICC-ES AC495 outlines the acceptance criteria for evaluating cold-formed steel structural beams that act compositely with cast-in-place concrete slabs through the use of steel angle anchors. This type of construction is often used in multi-story buildings and other structures where lightweight and efficient framing systems are desired. The scope of AC495 includes:
  • Material properties: it specifies the requirements for the materials used in the composite beams, including the cold-formed steel sections, steel angle anchors, and concrete. This includes requirements for steel grades, yield strength, and other relevant material properties.
  • Design and manufacturing: it outlines the design criteria for the composite beams, considering factors such as beam dimensions, anchor configurations, and connection details. It also addresses the manufacturing process and quality control measures to ensure consistent product quality.
  • Testing: it details the specific tests required to evaluate the structural performance of the composite beams, including tests for bending strength, shear strength, and composite action between the steel and concrete.
  • Evaluation and certification: it outlines the process for evaluating and certifying cold-formed steel structural beams with steel angle anchors to ensure they comply with the acceptance criteria and can be safely used in construction.
By adhering to ICC-ES AC495, manufacturers can demonstrate that their composite beams meet the necessary performance and safety standards. It also provides valuable information to engineers, designers, and builders for selecting and incorporating suitable composite beams in their projects.
