Will any of the HITLI post-installed anchors work for dynamic loading like conveyor motors?
Hello,
Currently, there are no test standards for dynamic loading of post-installed anchors in North America. However, please reference the “2010 Hilti European Dynamic Design Guide,” which can be used as a reference during the design aspect of the project. Please click here to access the guide from the Hilti UK website. Specifically, please review the summary on Page 14, Section 2.4.6.
The design premise, for the HIT-RE 500 V3 and HIT-HY 200 adhesive anchors with threaded rod, is that in a high-cycle fatigue application with 2,000,000 cycles is that you would perform an ACI 318-14 Ch. 17 static anchor design, and the strength of the carbon steel rod in steel failure is reduced to 25% of the static capacity, and the concrete/bond strength is reduced to 55% of the capacity (for cored holes for HIT-RE 500 V3 this would be reduced further to 40% - see page 9 under Fatigue Behaviour of Adhesive Anchors). In PROFIS Engineering, the design would need to be such that the static utilization does not exceed 25% for the carbon steel rod and 55% for concrete or bond failure modes (40% for cored holes).
