How to repair a HSS steel column in a warehouse
(OP)
Hi, I have a client that ask me to look at a warehouse he is renting. Some of the columns have been hit by a forklift, some of them have a hole due to the impact. Other columns have a bent on one of the faces of the tube. Has anyone done any repair on something similar, the columns are 8X8X1/4. Do you guys cut the damage area and use plates welded to the existing columns?
Thanks for your help.

Using a reduced stress instead of using a reduced column capacity has always annoyed me

To repair the column, shore the area, straighten the bent section or cut out and replace. Check the connections above to see if compromised and for badly damaged columns, check welds for all members that are supported by that column....impact damage can crack weld at joist-to-beam or beam-to-column connections. Check all connections for displacement and make sure that the roof surface slope is restored to drain properly, if low slope or "flat" roof.
If you splice a column, you should use a complete penetration weld or provide reinforcing plates on partial penetration welds.

If the new operation does not require protection, then encasing in comcrete may cause some problems with operation and takes up floor space. I've used 'elephant feet' for numerous projects but generally only where forklift is used.
