RE: Identify steel I-beam

I don't think X-Ray will get you close enough for engineering dimensions. It's difficult enough to distinguish between a #4 bar and #5 bar with X-Ray. Besides, X-Ray is a difficult technology to work with. You pretty much have to clear the area for quite some distance. Sonar is probably just as effective, but will also not give you dimensions.

 

I recommend you chip and repair.

Irv,

 

        I believe you can take X-ray photographs of the column and measure the photograph.  Check with the people who do this sort of thing.

 

Regards,

Fellow Engineers,
Is there a way to determine dimensions of an I-beam, encased in a square concrete column, to find its elastic properties, instead of chipping out the concrete?
Thanks,
Irv
