Holes in Bottom Chord
Holes in Bottom Chord
(OP)
How do you generally handle holes drilled through tension chords by a contractor... I have a series of trusses that the electrical contractor has drilled a series of 5/8" holes through a 3-1/2" (2x4)...
Do you just consider the reduced area or do you check the moment caused by the change in centroid? Does anyone have a reference to this problem; it should be fairly common.

I was wondering if the location was usually considered, or if any stress overage was considered to redistribute at limit loading... assuming that there are no knots at the hole location if it's not centred.
