Gaps in slip-resistant connections
Gaps in slip-resistant connections
(OP)
Hi everyone!!!
I would be thankful if anybody answered my question regarding gaps in slip-resistant connections.
I am on a cement plant project and such connections are literally in all structures. The problem is that fabrication of steel elements is of very poor quality. The gaps are massive regardless of if it is beam to beam or column to beam elements. In case of beam to beam the connections can't fulfil their design purpose as gaps are so big that they became load bearing connections, so contractor's workers just stack bolt washers in the gaps....
Does anybody know a good method to solve the problem with the gaps?? Also, the structures are already erected so preferably it needs to be worked around it.
Thank you.

yes a pic would be helpful to understand the problem
There are some liquid shims...like this

Just to say , there are cases more sever that the one on the picture.
Guys, Thanks so much for your help.

Does not look like high strength slip critical bolts

I suggest you need to speak to the engineer / designer of the connections and determine whether they are slip critical (e.g. need a faying surface between end plates) or are bearing only.

As shown, the connections cannot work properly as slip-resistant or bearing connections. Filling gaps with tightly fitted shims might appear to be a solution, but would make no allowance for change in length due to temperature change, so member buckling could be an issue.
