The anchor bolt edge distance l be is measured in the direction of the applied load from the center of the anchor bolt to the edge of the masonry When the projected areas of adjacent anchor bolts overlap the portion of the overlapping area is reduced by one half for calculating A pt or A pv as shown in Figure 3
Holes require a special plate washer of 6 mm minimum thickness under the nut if the bolt hole is more than 3 mm larger than the anchor bolt diameter The oversize holes will accommodate reasonable misalignment in the location of the anchor bolts and allow adjustment of column bases to meet the tolerance requirement between column centres permitted in AS 4100
