>From your experience, can you provide any guidance as to when one might
use heat straightening vs heating with mechanical realignment?

You imply that there are relatively few people who are adequately
experienced at heat straightening so I assume that this is a very
expensive proposition and, therefore, not appropriate for the typical
damaged column in an industrial structure.

What degree of straightening might be achieved by each method? Would it
be possible to reasonably determine in advance when additional
reinforcing might be required?
