Hi,
I've got to sister five 17' long ceiling joists, due to removing a
bearing wall. I've done the engineering, and given the existing roof
construction, I've got two options that work:
1) Use double 2x6 select struct at 16" o.c.
2) Use 2x8 select struct at 16" o.c. with a 3.5" long by 1.75" deep
top edge end notch.
The selection is deflection...
