HILTI HUS3 Ultimate Performance Mechanical Anchor System

HUS3 Screw Anchor

Ultimate-performance screw anchor for seismic actions into ComFlor® 60 and 80
All data in Table 1 applies to:

• Correct installation. See anchor box or Hilti.co.nz for details including hole cleaning and installation torque
• No edge distance and spacing influence. Only one anchor can be used in the lower flute at a time with the min. spacing between anchors along the length of the flute to be at least 3 x hef. This datasheet does not give information for the design of fasteners in a group.
• f’c = 30 MPa concrete. For higher compressive strengths, the tension loads may be increased by (f’c /30)0.5
• αgap = 1.0 (no hole clearance between anchor and fixture) was used to in the formula VRd,s,deck,C1 = αgap x αeq x VRk,s,deck,C1 / gMs,V In case of connections with hole clearance according to EN 1992-4 Table 6.1, αgap = 0.5 should be used.
• Testing in accordance with ACI 355.2 and AC 193. Evaluated in accordance with AC 193 and EAD 330232 and EOTA TR 049

For anchoring into the upper flute, either use Table 1 data below conservatively or refer to ETA-13/1038. Additionally, C2 seismic performance category is not included in ACI 355.2 and AC 193. C2 seismic performance category may be designed in the upper flute using all guidelines and parameters provided in ETA-13/1038.
