Question

Modelling Stauff Clamp

Thank you for all your excellant answers to my previous questions. I've got another slightly tricky one for you.

How should a Stauff Clamp be modelled? These pipe clamps have a plastic liner and restrain lateral and up/down movement, but also axial movement (e.g. act like a line-stop) as the pipe is clamped. At a certain value of axial force the pipe will move through the pipe clamp, as static friction has been overcome. These maximum loads in the pipe (axial) direction are given in Stauff literature. For a DN100 heavy duty clamp this value is 14 kN.

Is there any way to model this phenomenon in Autopipe? e.g. a linestop or stiff axial spring, which will resist axial movement untill 14kN,, and then allow the pipe to move. This type of functionality is present with soil, e.g. resist to a certain force then allow movement - but is there a way to apply something similar with a pipe support?

Thanks for your help.
