Hello everyone.
So my main experience is in carpentry but have an avid interest in engineering so i tend to get a funny feeling when i see something that looks a bit strange.
A friend of mine recently had a load bearing wall removed which included a chimney breast. The roof pearl lines split at this area and on both ends they were propped bearing down on this wall. Also there were about 25 joists which were once supported by this wall.
Some builders came in an installed a big wooden beam to support all of the joists etc and one end of the beam was supported by a concrete wall. To my shock the other end of the beam traveled a distance of about 40 feet only to meet the roof at the other end where it had to be cut down to an angle corresponding with the roof. Since the beam could not reach that external wall because the roof was in the way they bolted the beam to a single 4 x 2 rafter. I know from my experience as a roofer that these rafters are held in place with 2 four inch nails into the wall plate.
I have included a picture to supplement my explanation of the situation. Basically all of the weight of this beam and all that it is supporting including the roof via the pearl lines is bearing down on this one rafter.
Shouldnt a beam like this be supported by either two load bearing walls on either end or at least some kind of pillar on either side?
