1 Introduction SEISMIC ANCHORS Seismic s Seismic s Seismic s Introduction This section of the Specifiers Resource Book provides you with solutions for postinstalled anchors where there is a Seismic/Earthquake performance requirement. Currently there are two international standards which are used to derive Seismic performance data for Mechanical and Chemical s installed in concrete. One standard is from the United States (ACI American Concrete Institute) and the other standard is from Europe (EOTA European Organisation for Technical Approvals). The European Standard for metal anchors under seismic action was introduced in April 2013 and provides Category 1 performance (i.e. smaller earthquakes tested to 0.5mm crack width & equivalent to current ACI 355.2/ACI test methods) and Category 2 performance (i.e. larger earthquakes tested to 0.8mm crack width). The following flow chart provides you with guidance on how anchors are Seismically Certified;

In summary, Mechanical & Chemical anchors can be seismically certified provided they are tested to the requirements of either standard. Proof of the certification can either be by a recognized report (i.e. ETA or ICC ESR) or a Certified Laboratory Test Report (i.e an independent test report based on an accredited laboratory s test results)

26 55.1 EPCON C8 SEISMIC REINFORCING BAR CHEMICAL INJECTION Seismic s EPCON C8 Reinforcing Bar 55.1 GENERAL INFORMATION Product EPCON C8 is a High Performance Pure Epoxy ing adhesive for use in Cracked and NonCracked concrete. For structures subject to external exposure, permanently damp or chemically aggressive conditions. Benefits, Advantages and Features European Technical Approval option1 for use in cracked and non cracked concrete ETA10/0309: Highest level of European approval for chemical anchors 100 year design life Approved for flooded holes Approved for floor, wall, & overhead applications Data for Sustained Loading CSTB Seismic Applications Report 3/12727 Greater productivity: s in dry, damp, wet or flooded holes No weather delays Fast,easy dispensing with high flow (pneumatic) mixer Jumbo dispensing cartridge 900ml Greater security: Highest performance in cracked concrete Versatile s all stud & bar diameters in all directions Oversized holes s in carbide drilled and diamond cored holes For tropical and Cold weather conditions. Greater safety: Low odour. Nonflammable. Fire Rated: Refer Fire rated anchoring section Installation PERFORMANCE RELATED Drill recommended diameter and depth hole. 2. Important: Use Ramset Dustless Drilling System to ensure holes are clean. Alternatively, clean dust and debris from hole with stiff wire or nylon brush and blower in the following sequence: blow x 4, brush x 3, blow x 4, brush x 3, blow x Insert mixing nozzle to bottom of hole. Fill hole to 3/4 the hole depth slowly, ensuring no air pockets form. 4. Insert rebar to bottom of hole while turning. 5. Allow Ramset EPCON C8 to cure as per setting times.
