Re: disortion from heating

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dr. Richard Avent, et al, of LSU published a report titled,
"Heat-Straightening Techniques for Repair of Damaged Structural Steel in
Bridges".

The phone number for the Engineering Department is 225-388-5731.

Hope this helps.
