Connection for C6 and C4

[jlyles]

We had a job where the customer changed from grating to floor plate. We had to go back and add beams for the floor plate. We used C6. In AISC 13th edition all double angle connections are two rows and all single plate connections are two bolts. Can we go to single row on the double angle connection and a single bolt for the single plate connections. The end reactions are less than one kip.

I recommend at least two bolts per connection no matter what. You can design them as two in the same row and check the strength that way. Be sure to check. One kip isn't much but it shouldn't be taken for granted that the connection works.

I have always heard that it is good practice to use at least 2 bolts per connection, and that is what I usually do myself. In fact it is a requirement on one of the codes I have worked with.

weld the angles to the channels, bolt them to the other member. or use a shear tab with 2 bolts beside each other horizontally.

I would simplify the connection by using shear tabs and at least two structural bolts per tab. I would make the shear tab as thick as the channel's web and maximize the height of the tab to be as near to dimension T as practicable.

Shear plate welded to the receiving beam. Two bolts in line horizontally. Back of channel to shear plate.

Agree with hokie66 but check the bolts as a couple to take the shear reaction at the welded end of the shear plate.
