Here are steps to be taken to change the position of calculated COG:

Model 1

1. After completing the model & loads, run a static analysis to check the COG of the structure.

2. In the list file, we can see the COG is (-0.29, 0.59).

    

Model 2

1. Note the coordinate of new COG from the origin. For this example, we will change the coordinate to (-1,1)
    
        

2. Delete all loads and add two new skid loadings. 
    (i) COG as load condition 1
    
          

    (ii) POINT1 the opposite direction of COG as load combination 2.

           
       
3. Verify the load application in the listing file:

    
   

Model 3

1. In the original model, reactions at joints are applied to change the COG to a new location.

    

2. Run the analysis, and you'll get to see the COG changed to a new location.
