12 5 2020 nbsp 0183 32 The design of anchor rods has become complex and cumbersome with the development of the ACI 318 anchoring provisions originally in the Appendix D of the ACI 318 11 and earlier and in the Chapter 17 of the ACI 318 14 and later This document covers the required steps in the process of the design of cast in anchor rods normally encountered in column Anchors with a 45 176 pivot angle have a swivel head which makes them best for use in walls and ceilings that have an angled pitch Note Capacity is for the anchor only Mounting surface will affect the ultimate capacity They include a threaded rod anchor for supporting a Anchor Ductility When an anchor s overall design strength for both tension and shear is equal to the design strength of anchor rod steel element and all potential concrete failure modes have design strengths greater than the anchor rod steel element design strength this anchor design is considered as ductile anchor design 2022 2 24 nbsp 0183 32 Grouted anchors Fig 3 may consist of headed bolts threaded rods with nut and washer at the embedded end block end anchor or deformed reinforcing bars with or without end anchorage Commonly used bolt diameters vary from 12 50 mm although larger bolts are sometimes used Grouted anchors are typically installed with a cementitious or polymerASME ASME B18 2 1 covering head dimensions for headed anchor bolts and ASME B1 1 covering Unified Inch Screw Threads can be purchased from Techstreet AISC The AISC Steel Construction Manual and ASIC Design Guide 1 Base Plate and Anchor Rod Design both possess useful information about the steel used in ASTM F1554

ASTM F1554 Specifications The specification for ASTM F1554 covers straight and bent headed and headless carbon carbon boron alloy or high strength low alloy steel anchor bolts also known as anchor rods The anchor bolts are furnished in three strength grades and in the sizes specified below Heading the anchor rods is the next process but this does not apply to all the anchor rods The head is supposed to create pull out resistance on the anchor rod The end which is not threaded is heated at around 2000 degrees and molded into a head Bending anchor rods at a right angle is done to produce a hook that will be embedded in the concrete Headed Anchor Bolts TSA manufactures headed anchor bolts in a variety of diameters lengths materials and finishes We also stock a large number of common sizes in both plain and galvanized finish We can also manufacture headed anchor bolts to your specifications with your choice of material diameter length thread length and finish 20 4 2020 nbsp 0183 32 The constant in both equations shows how much less pullout strength a hooked anchor bolt can provide Whereas the constant for a headed anchor bolt is 8 the constant for a hooked anchor bolt is 0 9 Additionally the nominal pullout strength of a headed anchor bolt only needs to factor the area of the load bearing member and the concrete strength 29 6 2020 nbsp 0183 32 Anchor bolts are designed to attach structural elements to concrete In our industry anchor bolts are typically used to attach steel to concrete One end is embedded into the concrete while the opposite end is threaded to attach structural support There are four main types of anchor bolts L shaped double end rods with plate headed and
