การทดสอบพุกฝังยึดคอนกรีต

The resistance determination testing report includes:

• Customer and jobsite information
• Fastener and base material information
• Installation and test equipment information
   

Test information and test results

• Load and displacement values
• Load versus time and load versus displacement graph
• Test pictures and comments per trial
   

Displacement measurement enables plausibility checks based on the load versus displacement relationship. It helps to ensure a more reliable assessment of tests regarding consistency and predictability of anchor behavior.

• Comparison of test trials within the same series
• Comparison of destructive or failed test trials with typical failure curves

The optional evaluation report includes calculated design resistance based on:

• EOTA TR
• British Standard
• DIBt TR (Germany)
• SIA (Switzerland)
  
• CISMA (France)
• STO (Russia)
  

There are two types of test – destructive and non-destructive.

Destructive tests

If the following criteria apply, destructive tests are the right choice:

• Damage to the base material can be accepted
• Base material is relatively homogeneous
• You aim to achieve the maximal achievable resistance

Destructive tests are tensile and/or shear tests up to the ultimate load of the anchor.

The minimum number of test trials is based on the chosen testing and evaluation method. Usually between 5 and 15 test trials are needed for a proper evaluation.

Statistical or simplified evaluation according to the chosen evaluation method.

Non-destructive tests

If the following criteria apply, non-destructive tests are the right choice:

• Damages to the base material must be avoided
• Base material is relatively inhomogeneous
• You don't need to achieve the maximal achievable resistance 

Non-destructive tests are tensile and/or shear proof tests to a predefined test load.

The minimum number of test trials is based on the chosen testing and evaluation method. Usually between 5 and 15 test trials are needed for a proper evaluation.

Calculated test load and simplified evaluation according to the chosen evaluation method.

The test report includes:

• Customer and jobsite information
• Fastener and base material information
• Installation and test equipment information
• Test information and test results:
  - Load and displacement values
  - Load versus time and load versus displacement graph
  - Test pictures and comments per trial

Displacement measurement enables plausibility checks based on the load versus displacement relationship. It helps to ensure a more reliable assessment of tests regarding consistency and predictability of anchor behavior.

• Comparison of test trials within the same test series
• Comparison of failed test trials with typical failure curves

The optional evaluation report includes documentation of test load calculation based on:

• British Standard
• SIA (Switzerland)
  

Tests to validate installation quality are tensile proof tests to a predefined test load that is not supposed to damage the fastening and the base material.

The minimum number of test trials is based on the chosen testing and evaluation method:

• Usually 2.5% or 5% of all fasteners in an application
• Minimum 3 test trials

Calculated test load and acceptance criteria according to the chosen testing and evaluation method.
