Proposal for U-Bolt-type supports - here for horizontal pipe axis in x-direction

1. Guide
From 10 to 20, DX=1000mm, support at 20.
a) Prefered variant: Y, Mu=0.3; Z (or Guide), Mu=0.3; without any gap,
b) Alternative: +Y, Mu=0.3; -Y, Mu=0.3, gap=1mm; Z (or Guide), Mu=0.3, gap=1mm
Usualy I prefer variant a) because of normal precision of piping installation work on site and because of simplifying of numerical solution.

2. Fixed U-Bolt
From 10 to 20, DX=1000, support at 20.
a) Simple variant: X, Y, Z (or Y, Guide, Lim); without any gap, without any friction
b) Alternative I: Y, Mu=0.3; Z (or Guide), Mu=0.3; X2, K2=1, K1="blank", Fy=resistance force against pipe movement due to friction between pipe-beam and pipe-U-bolt from additional normal force of fixed U-bolt installation
c) Alternative II: Y; Z (or Guide); X2, K2=1, K1="blank", Fy=resistance force
If the simple variant model is not suitable I prefer the 2nd alternative variant.
