Minimum Edge Distance for Punched, Reamed, or Drilled Holes ..... 3 2. It is not a structural connection, but it is for mounting of equipment lug or base plate. η = 1.5 . anchors are fixed in the centre of the bottom plate, the distance between anchors and the slab edge may be insufficient to withstand the forces on the wall framing. Test Fixture ..... 11 3. Single-Bolt Tests ..... 8 4. Test Specimens ..... 7 2.

Plates thicker that (1) punch diameter will not punch well, also, so the rule of thumb depends on plate thickness in some degree with drilling required based on plate thickness. Code of practice for design. 1 Concentric Connections . Moment resisting connections will be dealt with in the next chapter. This edge distance is used in calculation of the bearing resistance of the fastener, so just using actual above value in that eq will solve my problem? The maximum sizes of holes for bolts are given in the table below, except that larger holes, required for tolerance on location of anchor bolts in concrete foundations, are permitted in column base details. AISC Specification J3.10 indicates the bearing strength of plates at bolt holes. Description: Very useful and easy to use spreadsheet for designing all common types of holding down bolts. This is also known as a "blowout" of the base material. If a 90 mm bottom plate is used and the . Comparison of 5/8 in. I~ I I I I I I I I I I I I I I LIST OF FIGURES Figure Page 1. The given edge distances (1.25 in.) bolt to the edge of the connected part is given in Table J3.4 on page 16.1-61. Notes; BS EN 1993-3 2005 supersedes this standard and the edge distances in this standard seem to be a bit less than the ones I have listed. Effect of Abandoned Holes on Capacity of Wedge Bolts.pdf. Fastening Technology 3.0 Anchoring Systems 18 Hilti, Inc.

Anchor bolt edge distance 1.75 inches or 2.75 inches, dependent upon sill plate Testing protocol monotonic versus pseudo-cyclic Wood-concrete interface condition friction versus “frictionless” membrane To properly generate test data for the purpose of assessing behavior, a new displacement based loading protocol was developed. Bolt Edge Distances. Keep in mind that these are minimum requirements, that is, not to exceed spacing. One bolt needs to be located no more than 12 inches (305 mm) or less than 4 inches (102 mm) from each end of the plate section. Joined May 12, 2010 Messages 1,704. b e = Effective width of flange per pair of bolts . The minimum values are: e 1 ≥ 1.2 d 0 , e 2 ≥ 1.2 d 0 , p 1 ≥ 2.2 d 0 , p 2 ≥ 2.4 d 0 , where d 0 is the diameter of the hole, e 1 , p 1 are measured parallel to the load transfer direction and e 2 , p 2 are measured perpendicular to the load transfer direction. Anchors, University Study, Reference. Comparison of 3/4 in. Therefore, minimum edge distance requirements are satisfied. Friction between base plate and the grout or concrete surface n u c c V P f A ` m 0.2 The friction coefficient (m) is 0.55 for steel on grout and 0.7 for steel on concrete 2. Edge Distances. Because the base-plate holes are oversized and the anchor rod is rarely centered in the hole, a heavy plate washer is required as illustrated in Figure 7.1.6-1(a); see also 7.2.4. Additionally, bolts should be placed within the middle third of the width of the plate. But as per the Eurocode EN 1993-1-8, min edge distance shall be 1.2 times hole dia. > both. c minimum edge distance, effective width, length ccr,N critical edge distance, ccr,N L 1.5 hef cw drag coefficient d diameter db diameter of the bolt dh diameter of the head of headed stud ds diameter of the shaft of headed stud ds,re diameter of the stirrup ds,nom nominal diameter of the anchor shaft dw diameter of the washer Tensile Tests ..... 6 3. The connection is also used at the base of the column where a base plate is connected to the foundation by means of anchor bolts. M. Mark K Platinum Member.
