Hey...I have a question...looking for a little help

Basement I Beam 8" spaning almost 16'
9" (measures 8' 3/4" ) Joists notched at the top to fit inside the I Beam
Block foundation to beam span is 15.5' on one side and 14.5' beam to block wall on the other side....

Two jack posts showing signs of stress....bending at center...

Call a structural engineer.

Hi,

The fact that it raised a question in your mind is the tell. If you are measuring stuff like that and trying to calculate loads you are doing engineering and that's not what we're supposed to do.

Tell the client something like, "I'm reall uncomfortable with it. I'm not an engineer, so I can't tell you with certainty that it's wrong; but if there's enough force there to bend those posts I'm pretty sure things are overloaded here and to to be certain you're going to need to get an engineer to look at this."

Hell, even if I had a formula in front of me that told me how to figure that kind of stuff out, I know I'd screw up the math anyway and get it wrong, so I have to go with the limited training and experience I have for this kind of thing and trust the hair on the back of my neck. After you do this long enough, you develop something - I'm not sure what it is - let's call it inspector insight, that just says, "Wrong!" Once you learn to trust it and match it to a sensible recommendation, things like that are easy.

ONE TEAM - ONE FIGHT!!!

I have no idea what you're describing. Is this some kind of code?

More information about the structural components is needed to understand what you are describing.

Even if someone had all of the information about the components, the loading onto the structure needs to be determined before anyone could even attempt to determine the cause of a problem.

Like others have said, time to punt.
