Moving Load Generation

Hi,

I am using STAAD to model wheel loads for the first time and having a little bit of trouble.  My model has W8x28 spaced at 5' on center and has L3x3x3/8 diagonals between them.  Two W24s supports the W8x28s.  The W8x28 support grating which the vehicle drives on.  When I set up the moving load, it applies it to both the angles and the W8x28.  How do I program STAAD so that the load is only transferred to the W8x28s?
