Proper way of Modeling

[EngrSBS]

Hello there friends,

I need some help with this problem. We designed a 2 Storey Building, it turned out just fine. Then my Superior said that release m33 of simple beams and the end of a continuous beams. also he said model the Raft Foundation at the base so I did it. then after this I encountered lots of errors and I don't now what to do..
1. the building becomes unstable
2. have shear and torsion failure on beams
3. and capacity ratio failure on columns
any idea where did I go wrong here.

thanks..

See if there is a loose joint or there is any unrestrained DOF.

check the area spring of your raft in which direction you made it. U should have springs or restraints in the 3 directions in order for your building to be stable.
