I created a mat foundation on piles with fixed head condition. I needed to see the moments at the piles (the spring support moments). Staad foundation does not give this. So I went in the generated staad pro file to view. 

It appears as though all the applied moments to the mat foundation DO NOT match the applied moments in the generated staad pro file and are a lot greater than the original. Please explain this ASAP. 

For instance a Baseplate moment for 

node 1 - LC 11 - DL was MX=0.2k-ft and MZ=-0.2k-ft as the applied load in the staad foundation model. in the generated staad model with corresponding node the applied moments became MX =-19.177 k-ft MZ=16.85 k-ft

node 6 -LC 24 - DL was MX=0.2.88k-ft and MZ=-21.84k-ft as the applied load in the staad foundation model. in the generated staad model with corresponding node the applied moments became MX =-12.465 k-ft MZ=543.6 k-ft

Please explain why there are such big differences.

Both are in kip-ft. and in my opinion both should be the same. How does staad fdn design based of the generated staad pro file I have a concern that the loads are not being transferred correctly/foundations not being designed properly.
