PEM - Fire Damage
PEM - Fire Damage
(OP)
See attached photo. The beam, in particular the bottom flange, is twisted noticeably to the right.
Overall there was no heat damage or buckling observed in this building. End walls blew out including the columns, but all frames in this area were ok. A lot of collateral damage and soot but members are straight. Is it possible that this visible twist was present before the fire?
Easiest fix to just replace? Heat straightening?

If a section has plastically deformed from the fire...replace it.

I don't have much faith in testing the hardness values. I believe that there is probably enough variation in values that without having a pre-fire calibration it wouldn't be informative. Regardless I don't see any indication that temperatures or duration were near the point to cause plastic deformation.

If the original supplier is around, you may want an opinion from their engineer and what is required to warranty the building... building could be old enough or supplier is 'gone'... that there may be no warranty in the first place.
