ICC-ES AC444
Full Name
ICC-ES AC444 – Acceptance Criteria for Steel Sandwich Plates Used as a Roof, Floor or Bleacher (Terrace) System
Scope
ICC-ES AC444 outlines the acceptance criteria for evaluating steel sandwich plates (SSPs) used as roof, floor, or bleacher (terrace) systems. SSPs are composite structural elements consisting of two steel face sheets bonded to a lightweight core material.
The scope of AC444 includes:
- Structural design: it specifies the requirements for the structural design of SSPs, including their dimensions, material properties, and connection details.
- Performance requirements: it establishes minimum performance criteria for SSPs to resist various loads, such as gravity loads, wind loads, snow loads, and impact loads.
- Testing procedures: it details the testing methods used to verify the performance of SSPs, including flexural tests, shear tests, and impact tests.
- Fire resistance: it addresses the fire resistance requirements for SSPs used in different applications, based on the applicable building codes.
- Quality control: it requires manufacturers to have quality control programs in place to ensure consistent product quality and adherence to the acceptance criteria.
By adhering to AC444, manufacturers and designers can ensure that steel sandwich plates used in roof, floor, or bleacher systems meet the necessary performance and safety requirements for their intended applications.
