Limitations to checks of anchors

Questo articolo è disponibile in:
When performing checks of anchors, the user can welcome a summary of checks that are not performed due to the configuration of the anchors. The description is provided for the following codes: EN, AISC, CSA, AS, and can be found on top of the formulas for anchors and in the report.

Eurocode

Anchor type: Straight

Message:

The following checks of anchors loaded in tension are not provided and should be checked using the information in the relevant European Technical Product Specification:

  • Pull-out failure of fastener (for post-installed mechanical anchors) – EN 1992-4, Cl. 7.2.1.5,
  • Combined pull-out and concrete failure (for post-installed bonded anchors) – EN 1992-4, Cl. 7.2.1.6,
  • Concrete splitting failure – EN 1992-4, Cl. 7.2.1.7.

Concrete blow-out failure is provided only for anchors with washer plates.

Anchor type: Washer plate

Message: 

Concrete splitting failure should be determined by EN 1992-4, Cl. 7.2.1.7. The information from relevant European Technical Product Specification is missing.

AISC (LRFD)

Anchor type: Straight

Message:

The following checks of anchors loaded in tension are not provided and should be checked using the information in the relevant Technical Product Specification (based on the 5 % fractile of tests performed and evaluated according to ACI 355.2):

  • Pull-out failure of fastener (for post-installed mechanical anchors) – ACI 318-19: 17.6.3,
  • Bond strength of adhesive anchor (for post-installed bonded anchors) – ACI 318-19: 17.6.5,
  • Concrete splitting failure during installation should be evaluated by ACI 355.2 requirements.

Concrete blow-out failure is provided only for anchors with washer plates.

Anchor type: Washer plate

Message:

Concrete splitting failure during installation is not checked and should be evaluated by ACI 355.2 requirements.

CSA

Anchor type: Straight

Message:

The following checks of anchors loaded in tension are not provided and should be checked using the information in the relevant Technical Product Specification (based on the 5 percent fractile of tests):

  • Pull-out failure of fastener (for post-installed mechanical anchors) – CSA A23.3-14: D.6.3,
  • Bond strength of adhesive anchor (for post-installed bonded anchors) – CSA A23.3-14: D.6.5.

Concrete blow-out failure is provided only for anchors with washer plates. Anchors shall satisfy the required edge distances, spacings, and thicknesses to preclude splitting failure as required by CSA A23.3-14: D.9.

Anchor type: Washer plate

Message:

Anchors shall satisfy the required edge distances, spacings, and thicknesses to preclude splitting failure as required by CSA A23.3-14: D.9.

AS

Anchor type: Straight

Message:

The following checks of anchors loaded in tension are not provided and should be checked using the information in the relevant Technical Product Specification (testing according to AS 5216:2018: Appendix A):

  • Pull-out failure of fastener (for post-installed mechanical anchors) – AS 5216:2018: 6.2.4,
  • Combined pull-out and concrete cone failure (for post-installed bonded anchors) – AS 5216:2018: 6.2.5,
  • Concrete splitting failure – AS 5216:2018: 6.2.6.

Concrete blow-out failure is provided only for anchors with washer plates.

Anchor type: Washer plate

Message:

Concrete splitting failure should be determined by AS 5216:2018: 6.2.6. The information from relevant Technical Product Specifications (testing according to AS 5216:2018: Appendix A) is missing.
