I am analyzing a condenser cooling water buried piping, which main pipe size is OD 2524x12thk.& branch pipe size OD1524x12thk. and OD724x12thk.

After passing through buried pipe modeler I have specified the anchor near to above ground piping to avoid transferring of forces /moments to condenser.
Now I get stress on above branch joints around 200% in Ope.and Exp.condition. To reduces the over stress I have been advise to provide 500mm RCC encasing over main pipe.

Now I want to know how to model 500mm RCC in Caesar-II and also I want know the calculation. We. don't want to modify the layout. Please let me know how to analysis the system.
