Question about unloading of slip critical bolted connection due to tension
Question about unloading of slip critical bolted connection due to tension
(OP)
Hi all,
In AISC 13, J3.9 Combined tension and shear in slip critical connections there is a factor to derate slip resistance due to tension on the joint.
In eqn J3-5. the term Ta for tension force.
In a preloaded joint, is this the total external applied tension force. or is it the tension force seen by the bolt (~20% of the total external tension force)? or is it the tension force seen by the joint (the remaining ~80% of the total external tension force)?
My machine design text book tells me I use the tension force seen by the joint vs preload when checking for separation of the joint, but doesn't touch on joints in combined shear/tension
Regards
JG
