HI,

I am designing the horizontal vessel which supprots the column. The nonzzle on which the column is mounted is perfectly above one of the two saddles.

My problem is that the soft doen't allow me to model both at same time, so in this case i am trying to manupulate calculation of saddle, by placing column weight (operating weight as dead weight) directly on the saddle. So that the equivalent forces due to dead weight and earthquake forces can be manipulated.

Please note that this equipment is critical so please guide me that this method is satisfactory or not.
