When applying compression force only in a beam to column moment connection, RAM applies the complete compression force to the flange of the haunch only. Moreover, it considers the flange as a slender plate not welded to the web.
My question is:
1. Why does RAM applies all compression force to the haunch flange only? (My understanding is that it should be distributed equally by area method and both the beam and haunch will resist such a force)
2. Why does RAM considers the haunch as a single plate not attached to the web and the beam above?
I attach a copy of the model with some snap shots.
