Joist to Beam Woes...

[strugglingstructural]

I have a model where the defined floor loads are being applied to the joists, but the joist reactions are not being transfered to the main beams. Because of this, the columns are not receiving any load from the beams. I am using steel joist design for my infill beams and steel frame design for my main beams. Does anyone know what condition is making this happen?

You must have common joint between joist and beams at intersection of end of joist and the beams .
hope this can help.
