OUR FIRM IS PRESENTLY FABRICATING A BRIDGE GIRDER THAT IS CONSIDERED FC. THE MATERIAL IS ASTM A 36 STEEL. THE GIRDER IS SHAPED LIKE A "PORK CHOP" AND REQUIRES A 9 FOOT RADIUS IN A 3' PORTION OF THE BOTTOM FLANGE. WE ALSO HAVE AN ACCESS DOOR THROUGH THE WEB THAT IS CIRCULAR AT THE TOP AND BOTTOM AND REQUIRES A COAMING AROUND THE CUT-OUT IN THE WEB. WE INTEND ON COLD FORM DEVELOPING THE FLANGE IN A PRESS BRAKE AND COLD ROLL FORMING THE COAMING. AWS D1.5 PARAGRAPH 12.12 STATES THAT COLD BENDING IS PROHIBITED ON FC STEELS. HOWEVER THE PARAGRAPH GOES ON TO DESCRIBE STAIGHTENING, CURVING AND CAMBERING FINISHED FCM'S THAT ARE ROLLED. IT ALSO DESCRIBES MATERIALS THAT ARE BENT DISTORTED OR CAMBER THAT IS OUT OF TOLERANCE. WE DO NOT THINK THAT THIS APPLIES TO THE PROCESSES THAT WE ARE PERFORMING.

ARE WE CORRECT? ANY PREVIOUS DETERMINATIONS BY AWS ON THIS MATTER?
ANY TOUGHTS? PLEASE RESPOND! CARL DUCOTE 504 466 2368
