ICC-ES AC133 is the ICC Evaluation Service acceptance criteria for mechanical splice (coupler) systems that join steel reinforcing bars in concrete construction. To match this to your program, talk with our team.
What ICC-ES AC133 Covers
The criteria define how mechanical rebar couplers are evaluated for strength, slip, and fatigue so that a spliced bar performs like continuous reinforcement. It is used to earn an evaluation report for a coupler system.
How Couplers Are Tested
Coupled bar assemblies are tested in tension for strength and measured for slip across the splice, and often under cyclic and fatigue loading, to confirm the joint meets the required performance categories.
Preparing Specimens
Full-size coupled bar assemblies are tested, so high-force grips and fixturing suited to reinforcing bar are needed. To configure rebar coupler testing, request a quote.
