SHORT ANCHOR BOLTS
(OP)
The case we are facing involves three columns whose anchor bolts were misplaced resulting in a situation where the top of the anchor bolt is below the top of the nut. Is plug welding into the nut an acceptable fix? or alternatively Is welding the nut to the base plate a good fix?
Thank you all for your opinions

1. Extend by welding a threaded rod
2. Use a coupling nut
3. Cut and use epoxy anchors
4. Weld base plate to rods
5. Perform analysis for threads engaged

THE END OF THE STORY IS THAT THE PIERS IN QUESTION WERE TOO HIGH.
I HAVE ORDERED THE PARTIAL DEMOLITION OF THE TOP OF THE PIERS, OF COURSE THE STEEL STRUCTURE HAD TO BE TAKEN DOWN.
FORTUNATELY WE WERE AT A STAGE WHEN IT WAS POSSIBLE TO DO THAT.
