"Anchor Bolt Design for Shear and Tension," Engineering Journal, American Institute of Steel Construction, Vol. Headed Anchor Bolts Bent-Bar Anchor Bolts ASTM A307, Grade A • ASTM A307: no specified yield strength • TMS 402 Commentary Concrete is cracked 2. is at least 14 days old prior to tightening the anchor bolts in order to prevent bolt rotation. General Anchor Bolt Information 5. ANCHOR BOLT DESIGN Combined Tension and Shear Anchor bolt design based on Code Abbreviation ACI 318-08 Building Code Requirements for Structural Concrete and Commentary Appendix D ACI 318-08 PIP STE05121 Anchor Bolt Design Guide-2006 PIP STE05121 Code Reference Assumptions ACI 318-08 1. The aim of anchor bolt design is to produce an anchor bolt connection analysis and design of adequate safety and serviceable level in its design life, both at a sufficiently and acceptably low probability of violating the limit states. (1980). 17, pp. Combined Tensile & Shear: When the anchor bolts are subjected to both Tensile and Shear loads we follow Section J3.7. CMU wall; threads excluded from shear … The verification for the two anchors close to the edge is done for an edge distance of c 1 and half the shear load (Figure 8a), while the proof of the two anchors remote from the edge is carried out for an edge distance of c = c 1 + s 1 and the entire shear load (Figure 8b). Anchor bolts are designed for combined shear and tension loads; the area of steel re quired for tension and shear is considered additive. ANCHOR BOLT DESIGN: Combined Tension and Shear: Result Summary ... Anchor bolt washer shall be tack welded to base plate for all anchor bolts to transfer shear… Understand the design of anchor bolts in shear. For combined tension and shear loading of anchor bolts in masonry, both working stress design (WSD), Equation 1, and strength design (SD), Equation 2, methods use a linear interaction between tension and shear design strengths. bolt (fy=36ksi) embedded 6 inch in top center of 8 in. Anchor Bolts - Combined Shear and Tension Allowable Stress: (8.1.3.3.3) 1 v v a a B b B b Strength: (9.1.6.3.3) 1 vn vf an af B b B b Structural Details 15 Anchor Bolts: Shear Example Given: 1/2 in. Revised the verbiage for “Do not evaluate concrete breakout in tension/shear” checkboxes to “Ignore concrete breakout in tension/shear”. Hippo-I don't have the 3rd edition LRFD, but J3.7 in the new 13th edition is also combined tension and shear in bolts. 4. I wouldn't have a problem using the same formulas for anchor rods (F1554) as for bolts (A325 or A490). Kharod, Umesh J. We re-organized Equations J3-3a and J3-3b to solve for the Shear Capacity based upon the actual tensile stress that is being applied to the bolts: Shear Capacity = 0.75*(Fnv / Fnt) * (1.3*Fnt – ft) {Eqn J3-3a} Criteria will be presented such that either Working Stress Design (WSD) or Ultimate Strength Design (USD) may be Understand the design of anchor bolts in combined tension and shear. 22-23.
