FIXING RENTRANT CORNERS ON BEAMS; ANY ID

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Robert,

Flame cutting with a hand-held torch can replace one re-entrant corner with a 
whole bunch of re-entrant corners which would have to be ground smooth.

Can a section of the web with the re-entrant corner be cut out and shop 
fabricated pieces with properly radiused corners welded in with full pen 
welds?

appropriately cut (in the web) with a nice radius (i.e, the nasty reentrant
corner).  Unfortunately a lot of these beams have been put in place and the
contractor is wondering if he can "fix-it" in the field.  Does anybody have
any ideas how this can be handled ?  Does AISC have any position on a method
of correcting this problem after initial fabrication ?

Thanks in Advance
