! E5 L( Q4 P* D% @- E6 }9 a5 Q1. sub floor did not hold tight to the floor joists. Screws are doing better than nails for this purpose., y# |8 M/ I& a0 p5 b

For 2, you may need someone with engineering knowledge to find out, but there should be a building code governing the span distance. For 3, you can go down the basement to do a visual check yourself.; }" S: X% {. E+ C$ \% G
