LEAP STEEL. SW REACTIONS AT SUPPORTS.

Hello, I am currently working on a leap steel model and I am having some troubles when calculating the steel reactions at bearings.

Although all steel members are similar, I am obtaining quite different values of Fy (kips) when calculation steel weight.  It seems that the load is being concentrated in one of the girder supports:

I have ran the grillage model analysis as well as the Finite Elements Method analysis but the problem is not solved. Do you know how can I solve it?

Please find attached a word file where can be show the problem in several figures.

Thanks,
