ICC-ES AC427
Full Name
ICC-ES AC427 – Acceptance Criteria for Cast Connex High Strength Connectors for Use as Bracing Connections in Accordance with AISC 341
Scope
ICC-ES AC427 outlines the acceptance criteria for Cast Connex high strength connectors used as bracing connections in steel structures, specifically in accordance with the American Institute of Steel Construction (AISC) 341 Seismic Provisions for Structural Steel Buildings.
The scope of AC427 includes:
- Materials: it specifies the requirements for the materials used in the connectors, ensuring they meet the necessary strength and durability standards for seismic applications.
- Design and construction: it details the design and construction requirements for the connectors, including their dimensions, tolerances, and load-bearing capacities.
- Performance: it outlines the testing methods and acceptance criteria for evaluating the performance of the connectors under seismic loads, ensuring they can withstand the forces and deformations expected during an earthquake.
- Installation: it provides guidelines for the proper installation of the connectors, ensuring they are correctly connected to the structural members and can function as intended.
- Quality control: it establishes a quality control program for manufacturers to ensure that the connectors consistently meet the requirements of the acceptance criteria, including inspections and testing procedures.
The AC427 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their connectors comply with the AISC 341 Seismic Provisions and are suitable for use in seismic applications.
