Hi,
I have a horizontal arm connected to a pipe using U bolt,
Does anyone knows how to calculate the rotational capacity of this connection type?
I believe that is has something to do with the friction coefficient between pipe and the U-bolts, and also the tension capacity of the U-bolt but i do not know how to how to link it together.
Any advice will be much appreciated.
Thanks.
Ilan.
If you want to transmit any torque (rotational capacity) I would recommend some other connection (such as a drilled hole through the pipe). As you tighten the U-bolt the pipe will just deform. Even if you are able to get it tight enough to work the first time it won't continue. Once it slips the first time its capacity is greatly diminished.
Hi jboggs,
This is a given situation, i have no choice.
this type of solution is often used in telecom towers (masts).
I the torque capacity of one U-bolt is not enough then is can put two or three.

I the torque capacity = IF the torque capacity
I would trust real world experience more than any calculations. Too many variables (coatings, deformation of pipe and bolt, nut torque, etc.).
