I'm wondering why there's moment on column and over support unless this isn't rigid joint , it's hinge
i tried to fix it by using advanced bar options but there's instability , what is the solution ?
thanks in advance
Your structure wasn't released at the connection slab/beam/colum, now it is at top of the column.
If you don't want bending moment at all in the colum you have to release the column. If you release the beam then bending moment will still pass through the FE connection between slab and column.
Look at this !! and why you bracing the column ??
curious, I had no instabilities in the file i sent. where is this node?
for the bracing : I made an hinge at the top of each column, as it is hinged at the bottom, the structure is unstable if you do not brace it.
i don't want design frames ! ( deep beams ) .. i design hidden beams .. hinge joint at top and bottom .. why the structure is unstable ?? that's not true
I am sorry but do you find this is stable ?
If you hinge your column top and bottom then you need to brace somewhere.
Fix your column at the foot if you don't want bracing but hinge at the top.
