PROFIS Anchor Seismic Calculations

Precision solutions for anchor seismic design.

Why start from scratch to evaluate, select and design anchor systems for seismic applications, when you can take advantage of our years of experience and research in anchoring system seismic performance?

Performing seismic calculations according to ACI 318-08, Appendix D design methods is as easy as using Hilti PROFIS Anchor Design Software. We have designed PROFIS Anchor Earthquake Calculations to integrate a variety of detail that helps you calculate performance expectations. Simply select a design method, indicate seismic design and enter the appropriate seismic design approach.

Ductile Anchor Yielding

When you select the steel strength of a ductile anchor element as having the highest percent design utilization, the PROFIS Anchor Earthquake Calculations will filter the solution for products that satisfy the ACI 318-08 definition of a ductile steel element. If the ductile anchor yielding is not the limiting resistance, you are automatically protected. The software will generate a design report output stating, “Fastening does not meet the design criteria.”

Ductile Fixture Yielding

You can also choose that the fixture being held in place by the anchor will be the limiting resistance in the design, and yield in a ductile manner. For that approach, we have enabled PROFIS Anchor Earthquake Calculations to make the appropriate adjustments when you input the corresponding loads of the anchor-attached element.

Non-Ductile Failure

When your jobsite applications call for a design with non-ductile failure—corresponding to a limiting design resistance of brittle steel, concrete failure, or anchor pullout—PROFIS Anchor Earthquake Calculations can also apply the appropriate reduction factor to the design strength according the ACI 318-08 code. This is often necessary for common jobsite applications with limited edge distance and anchor spacing.
