Siby,

You might be looking for support design details that CAESARII does not have the specifics.

A 'Y' restraint that might be considered for small size piping could be a simple U-bolt to the structural steel. This is not easy if the structure support is concrete beam. An imbedded plate is needed then for U-bolt.

Small size piping on a rod hanger can be made to a 'Y' restraint with a steel angle or channel shape fastened to the rod hanger with U-bolts to stiffen the rod hanger. Another steel angle or channel shape in the horizontal/lateral direction could restrain the lateral direction to act as a guide. Some designs use steel cables to restrain the lateral movement of a rod hanger. If the pipe sizes are too large for a U-bolt, then a 'box' of steel angle or channel shapes could restrain vertical and lateral movement.

The pipe shoes are not necessary. If there is insulation on pipe, then installation of the pipe shoes would make sense.
