I'm doing an bridge analysis. It is a typical deck-stringer-floorbeam-girder system. The girders are simple supported, pin on one end and roller on the other. I offset all the beams below the deck in different distance which matches the real case. The deck is connected to the stringers by rigid link. The results show large axial forces in almost all the beams. If I delete all the offset, the axial forces are gone. But I don't think it is a good way to do this because it obviously doesn't fit for the real case.
I tried to release Fy, Fz and all moments in the rigid links, the axial forces are gone, too. But I'm not sure if it is right because the moments in transverse floor beams look very small.
I read some of posts here, esp. by edward1, but didn't really understand it. Could somebody here help me with this situation? what should I do?
