The Good Engineering Practice says that the minimum distance between the edge of the hole and the edge of the baseplate should be sufficient to accomodate the anchor bolt washer. The size of the Drop-in Anchor refers to the diameter of the standard UNC threaded rod or bolt to be used with this fastener. Anchor’s ductility is its own characteristic related to anchor rod material, embedment depth, anchor bolt spacing and edge distances etc, and has nothing to do with the applied loadings. From a practical point of view, the clear distance for anchor bolts or anchor bolt sleeves to the edge of the concrete shall be a minimum of 100 mm. The Maxi-Bolt anchor has been rigorously tested. 1.4 for anchors in cracked concrete with edge reinforcements of a no. The shear-friction method uses distortion of the base and uplift in the rod and may be adequate to resist the base shear. The term anchor bolt, when used with ASTM A307 grade C, A325, or A490 material, however, only describes the first option for the following reasons: Yes. When the projected areas of adjacent anchor bolts overlap, the portion of the overlapping area is reduced by one-half for calculating Apt or Apv as shown in Figure 3. 1/4" is sufficient for this. Minimum Edge Distance for Punched, Reamed, or Drilled Holes Bolt Diameter At Sheared Edges At Rolled Edges. Per ACI 318 Appendix D 5.3.5, the pullout strength of a hooked rod is determined based on the bearing component only, neglecting any frictional component because crushing inside the hook will greatly reduce the stiffness of the connection. If larger uplift forces are present, an alternative column base detail, such as the boot in Figure 7.1.6-1(b) should be considered. • The versions with hook and eye bolt broaden the application spectrum. • The anchor can be easily and speedily installed with low efforts. 190 0 obj <>stream Example 1: Bolted Splice – Bolt Check 12.5.1 Geometry Factors, C • Edge distance = 3-5/8” • l/D =/D = lm /D = 151.5/1”/1 ” =15<6= 1 .5 < 6 • 1.5D minimum = 1.5” < 3-5/8” OK • C = 1.0 30 The coupon code has been applied to your cart!
