RE: Minimum steel connections

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Maybe that's why I practice "two bolt minimum". I cut my teeth on steel
design while working for a steel fabricator :o).

||I don't believe there is a specific two bolt minimum
||requirement per code,
||but it simply makes sense.  When the steel member is swung
||into position,
||the erector needs one hole for the spud wrench to capture and
||align the
||pieces and at least one other hole to install a bolt and
||"make".  Even if
||the bolts are only an erection aid for a welded connection
||two bolts ea. end
||should be the minimum.
