Steel Channel Web Local 'Pullout' strength
Steel Channel Web Local 'Pullout' strength
(OP)
The situation I am looking at is an insulator string assembly that is bolted perpendicularly to a hole in the web of a steel channel (channel is fixed at both ends with no other significant loading). The force from the bolt/assembly acts normal to the web.
I need to find a method to determine the minimum force required to cause local shearing or 'pullout' that would happen at the edges of the washer.
Any help much thanks,
Titus

To produce safe designs you maybe only need at most analyze the detail starting with a 3D model of the shape with the hole and other reasonable restraint and maybe eccentrical loading to one side.
Other modes of failure, particularly entailment effect of the cable may cause rupture there. This will be even more so true if fatigue makes to vary the angle at which the cable enters the anchoring outfit.

Search the net for the yield line analysis to get a guidance if you need it.
Hope this helps.

Supplanti has the best option.
A steel plate will fail in bending before it fails in shear for almost all reasonable s/d ratios.
