Minimum edge distance from center of hole to edge

Minimum edge distance from center of hole to edge

Minimum edge distance from center of hole to edge

(OP)
Where can I find a specification in te AISC or any book where specified the minimum edge distance from the center of hole in a base plate column to the edge of this base plate, I know in the table j3.4 of the manual say the minimum edge distance from the center o standard hole to edge of connected part but i´m not sure, it apply in the same way to the base plates or only in connection between beam column or bracese etc.

RE: Minimum edge distance from center of hole to edge

In the Canadian CSA S-16, Table 6 "Minimum Edge Distance for Bolt Holes" provides values for various size bolts. The required edge distance is greater for a sheared edge than for rolled, sawn or gas-cut edges.

For a 3/4" bolt, the value is 32mm for a sheared edge and 25mm for a rolled, sawn or gas-cut edge.

RE: Minimum edge distance from center of hole to edge

It had better be table J3.4 of the AISC otherwise I may be in trouble.

I believe if you look into some of the connection tables contained in the books and you will see they use the values in table J3.4

RE: Minimum edge distance from center of hole to edge

this sentences is from AISC Steel Design guid 1 " Base Plate and Anchor Rod Design":
Anchor rod layouts should provide ample clearance distance for the washer from the column shaft and its weld, as well as a reasonable edge distance. When the hole edge is not subject to a lateral force, even an edge distance that provides a clear dimension as small as 2 in. of material from the edge of the hole to the edge of the plate will normally suffice, although field issues with anchor rod placement may necessitate a larger dimension to allow some slotting of the base plate holes. When the hole edge is subject to a lateral force, the edge distance provided must be large enough for the necessary force transfer.[/b]
