Mislocated Bearing Stiffener
Main Member Type: | Rolled Beam, plate girder |
Attached Member/ Detail Type: | Plate Girder |
Error Type: | Bearing stiffener misalignment |
Description of Error: | Bearing stiffeners welded in place out of plumb. Kick is 1 15/16" in lieu of 15/16". |
Solution Recommended: | Since bottom location of stiffener above the sole plate is
correct and out of plumbness was less than 5%, stiffener was left in place and a shim used to bolt cross frame to stiffener. |
Required Final Checks / Verification: | Since bottom location of stiffener above the sole plate is
correct and out of plumbness was less than 5%, stiffener was left in place and a shim used to bolt cross frame to stiffener. |
Was Repair Successful ?: | Yes. |
Other Possible solutions: | Avoid removal unless absolutely needed so can avoid air arc
gouging and grinding in the high stress bearing area. 1) If bottom location of stiffener is within middle 50% of sole plate, leave stiffener as is and check plumbness. If out of plumb more than 5%, weld additional stiffeners to create a shear panel (space new stiffeners between 6" and 12" on center. New stiffeners half the thickness of bearing stiffeners). Check cross-frame connection clearance. 2) If bottom location of stiffener is not within middle 50% of sole plate, add 2nd bearing stiffener. |
