American Concrete Institute (ACI) Building Code 318 - Building code Requirements for Structural Concrete and Commentary ACI 318 / ACI 133 A CI 318 / ACI 133 Type of Test Required Why ! (purpose of the test) What is the Criteria ? Static tensile strength test Tensile strength of the Rebar joint (Rebar to Coupler Splice) joint   > 1.25fy for Type 1 100% fu & >1.25fy for Type 2   Fu = Ultimate Strength of bar Fy = Yield Strength of bar   Slip Test   Used to make sure that the plastic movement (slip) between the reinforcement bars with in the Mechanical Splice, when Loaded in tension   The bar-splice assembly shall be loaded in tension to nominal zero load, not exceeding 4Mpa (600 psi).   The bar-splice assembly then be loaded in tension with a loading rate between 70 Mpa/min to 690 Mpa/min.   ...

What are Reinforcement Coupler's Reinforcement Coupler's are used to join Reinforcement bar's that are used in Reinforced concrete structures, as a replacement for conventional lapping method of joining Reinforcement bar's. Mechanical Splice / Coupler's are  mechanical connections between two pieces of reinforcing steel that enable the bars to behave in a manner similar to continuous lengths of reinforcing steel bars. Mechanical splice join rebar end-to-end, provides many advantages of a continuous piece of rebar. Mechanical Splice  system is used in connecting Reinforcement Bar of respective/ different diameter using the respective Coupler's as per applications and standards/criteria.
