So I am a relatively new inspector and structural is my area of least experience.
I have a home with a structural wood beam in the basement which is being supported by the foundation wall on both ends and by two steel jacks intermediately spaced between the two ends.
My first question is: Are adjustable steel jack posts allowed for permanent installation? I didn’t think that they were, but not sure.
Secondly, this beam is in 3 sections. One break in the board is directly on top of one of the jacks. To me, this just doesn’t seem like it could possibly be correct from a physics perspective lol but I don’t know the hard and fast rules. The other break in the beam is farther away from the other jack, about 24-30 inches. Are support beams allowed to not be continuous? If so, what is the approved method for joining them?
Also noted was the sistered beams only being adjoined to each other laterally with nails. Should the individual beams not be sistered together with lag bolts such as ledger boards and such?
Many thanks for all your answers!
