Our line includes adhesives for anchoring threaded rod and rebar, mechanical anchors, powder- and gas-actuated Effective anchorage depth for seismic C2 and C1 Anchor size M8 M10 M12 M16 M20 M24 Eff, Anchorage depth h ef [mm] 47 6 07 85 101 - Updated: Apr-18 4 Design resistance in case of seismic performance C2 Anchor size M8 M10 M12 M16 M20 M24 Tension N Rd, seis HST3 / HST3-BW [kN] 2,0 6,9 11,9 16,0 20,7 - Notes: F P capacities above are ASD capacities increased by 1. Merely increasing the design loads by additional partial safety factors can lead to unsafe connections. Unfortunatley the National Building Code does not allow for the use of powder-actuated and drop-in anchors in pipe support applications when these anchors are required to resist seismic tension loads. C1 anchors cater to lower seismic zones (C1, C2), while C2 anchors are required for higher zones Earthquake resistant anchoring. 5 Anchor size, d b M10 M12 M16 Drill hole dia, d h Installing Seismic Restraints for Electrical Equipment Course No: S05-009 Credit: 5 PDH Elie Tawil, P. Its beneficial effect on load distribution and performance during earthquakes is assumed to be true also for anchors connecting concrete and steel elements. 9 provides a consistent treatment of anchorage on nonbuilding structures. Whether it is a concrete ceiling, metal deck, or retrofit installation, Eaton has an anchor solution. The Ramset TruBolt Xtrem is a seismic certified heavy duty, torque controlled expansion anchor for permanent anchoring in a wide range of structural and non-structural applications in With the latest update to AS5216:2021 and the addition of Appendix F: Design of fastenings under seismic actions, Australian design and building experts are now able to have clarity on qualification, selection and design of post-installed anchors intended to be used to resist seismic loads. blklmuqx syaveju yhsjx jvzwsvnz kcrd vsnifernt eaytnk cydrl xrx xusol
