2 car garage over unfinished basement.
2 6" steel beams running 21ft
1 screw column in the middle of each beam…neither column is anchored on either end.
ends of beams rest on foundation wall.
is there a problem with the bottom chords of the beams not being continuous???
Between the top of the beam and the ceiling looked to be a fiberboard material.
It’s only installed directly above the beams…rest of ceiling is concrete.
Possibly acting as a cushion???
ceiling in corner of basement under garage…no, the pic is not playing with your eyes.
garage floor is bowing in this area.
Garage floor definately flexes and vibrates when you jump on it.
What’s odd is that there was a hump all the way down the garage floor, but it was perpendicular to the beams.
Never ran into a suspended concrete garage floor like this.
Because of this and the factors listed above, I believe a Strucural Engineer is in order.
Any objections?..please share any input.
