Dear Friends,

In one of my project's Two Phase system,we are using Struts for Top Discharge of Pump. Line Size is 18", Pump Nozzle is 16".

While Strut Modeling, we received comments from client,as explained below.

Our company's model procedure :

From To
10 20

20 Restraint = Z Without Friction Factor.

Client Comment to use in modeling of strut Restraints
-Z ROD. without friction factor. Length =1800MM (required as per vendor drawing)

-Z(Minus) is the direction where Strut is going to install at site.

Query: We did & checked with -ZROD,however result is same,nothing changed,loads on Strut & Loads at Pump Nozzle are same with modeling both methods.

1) Which is the correct method for Strut?

2) If we model "Z" means it consider both + & -.& if model particular in one direction like "-", than how CAESAR consider for opposite direction?

Regards
