BS - 8110 - Coupler Testing Specification and Criteria

-

Coupler testing Specification, Criteria and Standards as per BS 8110

British Code - BS 8110 - Structural use of concrete

BS 8110

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

 

> 1.15fy

&

Bar break (100%fu)

 

Slip Test

 


Used to make sure that the plastic movement (slip) between the reinforcement bars with in the Mechanical Splice, when Loaded in tension



<=0.10mm after applying 0.6fy loading

 


Maximum % Elongation

 

 

0.1 mm after applying 0.6 fy loading

 

BS 8110

British Code has lower acceptance criteria as compared to the ACI code, 

It specifies tensile testing and slip test for the joint for acceptance of the sample.
