Refer to Tables 1A and IB for a summary of the various anchor bolt classifications and criteria for which design procedures are herein provided. Note that anchor bolts are defined as type A, B, C or D. These types represent various design conditions of anchor bolts such as spacing, edge distance and development length. anchor installation embedment anchor lightweight concrete lower flute of steel deck with DIA.

Rotational Capacity Test Checks bolts for overall capacity, proper lubrication, and for damage during storage or transit 2. Verification Test Demonstrates that Contractor's equipment & procedure will tighten bolts to proper tension 3. Inspection Torque Determines torque value to be used in the random field inspection 4. ACI 318 Appendix D provides methods of determining available pullout capacity for both types. This subject is discussed in Section 2.5 of AISC's Design Guide 1, Base Plate and Anchor Rod Design, Second Edition. Table 2.2 of the design guide lists anchor rod materials; see also Table 2-5 in the 13th Edition Manual. Kurt Gustafson, S.E., P.E.
July 2014 page 313 HSA stud anchor Design process for typical anchor layouts in non cracked concrete Background of the design method: Values of the design resistances are obtained from PROFIS 2.4.2 in compliance with ETAG No.001 Annex C Design Method. = embedment depth of anchor head measured from attachment of anchor head to tensile stress component, to the concrete surface, in. M. n = nominal moment strength M. u = factored moment load on embedment M. y = elastic moment capacity of steel plate n = number of threads per inch P. d = design pullout strength of concrete in tension P. n = nominal axial strength P. u
Strength of the steel bolt itself can come from ACI 318 or various other design codes. Strength of embedment would typically come from ACI 318 and would depending on the bolt and concrete details, not easily put into a table. In addition to bolt size varying, threading can vary, which has some effect on bolt area.
For specific bolt performance data, tensile and shear loadings please see the Screwbolts page of this website or contact us. The performance figures shown in the Technical Data on each of the product bolt diameter pages, in concrete, are supported by tests carried out to UEAtc M.O.A.T 49 1992 by Independent Test Houses (ITH).
