Dears,
I have a frame with 6 main supports( fixed). Earlier i used fixed but supports by releasing lateral forces (Fx & Fy) by giving slotted holes. Now i need to design by giving standard holes in base plate and by releasing forces at base support top end(stub end). I released Fx & FY and applied at support top side (3 110 TO 114 END FX FZ) but still it shows heavy lateral force. this lateral forces was zero when i provided fixed but at bottom side. please advise how it comes like that. Actuall there should not be lateral forces any more.
