Bolt and Nut with Vertical Axis Connecting Beam to Column
Bolt and Nut with Vertical Axis Connecting Beam to Column
(OP)
Hi everyone,
I should be grateful if someone guide me to a reference(e.g. AISC manual) which requires bolts being "over" nuts in bolted connections in order to prevent from falling in case of loosening due to vibration. I think assembling of bolt and nut in opposite (similar to the below picture is wrong.

When I'm concerned about the fastener loosening in the first place, I get serious about joint prep, fastener quality and installation torque. Some will correctly point out that torque as method of establishing fastener preload has "limitations." The more sophisticated methods of preloading fasteners can certainly be more accurate, but torque has its place.

This may be written somewhere, I don't know. I want to say it's just common sense.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

But, the first bolt going through a assembly of many bolts is going to depend more on the convenience of the steelworkers trying to wedge the joint together and getting it aligned while the steel is still on the hook and everything is "mobile, agile, and hostile." We don't know where the scaffolding was, where the steel was supported, where the man was, what was in the way, etc.

Because once the nut has loosened the joint has failed and attempting to standardize the performance of a failed connection is not useful.
