Examples
“A few of the other most common defects that I find are missing nails in joist hangers (brackets that support the floor structure), missing flashing at the rim (metal that keeps water from leaking in to the house), and improper load transfers.”
“(I recommend digging a earth around where a joist is to be hammered in initial to loosen it) 11.)”

“The length of this chain, the breadth and thickness of the joist, its height from the floor, and the circlet of chain on the neck, were accurately measured; and it was thus shown that the chain unoccupied by the circlet and the joist was a foot and a half longer than the space between the shoulders of the man and the joist above, or to that extent the chain hung loose above him; that the circlet (which was fastened so as to prevent its contraction) rested on the shoulders and breast, the chain being sufficiently drawn only to prevent being slipped over his head, and that there was no other place in the room to which he could be fastened except to one of the joists above.”
Dred; A Tale of the Great Dismal Swamp. In Two Volumes. Vol. II
“2 A joist is a support beam used in both floor and roof systems to support the decking material usually plywood over which the finished floor or roof is laid.”

“It was grounding out through the conduit with enough amperage to scorch the wooden joist.”
“This metal wire was attached at one end to the metal framework of the suspended ceiling and to a nail in the joist at the other.”
