"SAP2000 Bridge(Flyover) Modeling"
 
   I have modeled a flyover with discontinuous spans with 2 bearings at the bents by using the BRIM manues. The problem I am facing is that in analysis it shows some -ve moments in girders at the supports whereas I have connected the girders at base only and bearings are free to rotate. Could anybody please share his knowledge or experience about this perticular anomaly in my analysis. I will be highly greatful.
