An insurance company has hired me to investigate repair to an impact-damaged
bridge; concrete deck on four steel plate girders (48"?). Bottom flanges of
two girders were displaced laterally, maybe 3 inches, and locally buckled.
The girder top flange and the concrete deck appear unaffected.
My thought is that the girders could be (a) realigned using a combination of
force (applied to bottom flange) and heat (applied to flange and web) and
(b) "cut and paste" at the localized buckling. Of course the owner wants a
So, I'd like to find relevant information on this type of repair.
