Threaded Rod Load Bearing Capacity

There should be enough engagement between the bolt threads and internal threads that the bolt fails in tension before the threads shear.

Threaded rod load bearing capacity.

Proof loads and tensile strengths are computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread. Rod spec 1 2 100 3a 133 3b ibc 2006 09. The tension capacity of the bolt is given by. The tensile stress area a t is obtained from standards.

Hanger support spacing rod sizes horizontal pipes.

Loads on threaded rods thread type. When used for suspension they are threaded into an anchor in the ceiling and. If appropriate shear capacity must be reduced for large packings large grip lengths and long joints. Note that hangers supporting steam water air or gas piping systems should be able to carry the weight of piping insulation valves and other equipment.

Pre assembly of component modules. Threaded rods proof load capacities in metric units. Thread shear is an important failure mode for a bolted joint and occurs when the threads shear off of either the bolt external thread shear or off of the nut or tapped part internal thread shear.
