Mechanical Coupler Tensile Test

Mechanical Coupler Tensile Test
The Mechanical Coupler Tensile Test measures the tensile strength and performance of mechanical splicing devices used to link two rebar ends.  These couplers must function well under high tensile strains, with no slippage or fracture.  The test duplicates structural loading conditions and assesses if the coupler-transferred load is equal to or greater than the strength of the parent rebar.  This is essential for crucial connections in columns, beams, and seismic reinforcements, since it ensures that the joint functions as a monolithic element.

Advantages of Mechanical Coupler Tensile Test:

• Verifies the strength and performance of mechanical splices
• Ensures couplers meet or exceed rebar tensile strength.
• Supports structural integrity at key joints.
• Required for high-rise and seismic applications.
• Improves safety in precast and in-situ construction.
• Tests conducted under real-load simulation settings.
