This report presents state-of-the-practice set of guidelines for the determination of wind-induced forces and the design of anchor bolts for petrochemical facilities. For anchor bolt normally the anchor bolt holes on base plate are much bigger than anchor bolt diameter due to cast-in anchor bolt construction tolerance, while the anchor stud is rigidly welded to the base plate. The designer also needs to know whether the anchor is by itself or part of an anchor group—multiple anchors that will work together and that have equal embedment depth have slightly lower. When the projected areas of Figure 2—Minimum Effective Embedment Lengths Bent-bar anchor bolt Headed anchor bolt Grout Minimum clearance between anchor and nearest masonry surface: ¼ in. Minimum Embedment Depth in. Concrete Anchor Embedment Depth: 4-7/16 Inches. If you are using anchor bolts for concrete slabs or foundations it's important to place the bolt in the concrete so it's in the center of the wall. concrete bearing surface fully threaded anchor stud standard specifications 586-2 and 586-3. anchor material, anchor diameter, edge distance, spacing, concrete strength, embedment depth and for the effects of cracking. Considerations include: diameter and material type, internal thread length, minimum edge distance and required hole size. Anchor Bolt Holes Hole sizes for steel-to-steel structural connections are not the same as hole sizes for steel-to-concrete anchorage applications. the distance from the anchor to the edge. Ca1 - Distance from the center of an anchor shaft to the edge of concrete in one direction (in inch). The carbon steel anchor body, nut and washer have an electro-plated zinc coating conforming to ASTM Drive the anchor into the hole using B 633 to a minimum thickness of 5 μm. If short, the bolt capacity drops and the resulting KPA capacity drops as well. This accounts for a 6 ½ Titen Hd that goes thru the ¼ inch plate washer, the nominal 2x block, and through the full dimensioned 2x sill. 75 when anchors are placed in structural lightweight concrete. For 5/8" and 3/4" LDT Anchors, the critical edge distance for these anchors is 10 times the anchor diameter. ment depth, anchor spacing, edge distance, concrete strength, anchor steel type, and direction of loading.
