Hello Everyone,
I am designing a one story building where I came across a situation where I supposed to provide a secondary beam where load from one beam is supposed to be carried by other primary beams so as we generally used the partial moment release I did the same please check my model attached below to find if this method of moment release is correct.
In addition to that should I need to assign master slave specification in my model to assure it's rigidity?

You are only supposed to use moment release if the connection is a shear type connection with no moment transfer. Since you have a concrete structure, you may want to check what the connection of the secondary beam to the primary is like. If it cannot transfer moments, then applying release ( or partial moment release ) is fine. Also releasing MX ( torsion for the beam) is not a good idea. So when applying releases or partial moment releases, it is always advisable to do so for MY and MZ.
You don’t need master slave for defining connections between primary and secondary beams. If you are considering using master slave for modeling a rigid diaphragm ( a concrete floor slab or roof slab ) then yes, you can certainly use the SLAVE DIA ZX for that.
That means when releasing moment for secondary beam we must always release MY and MZ and not MX?I thought release is done considering Local axis which is displayed on the bottom left side of the screen
Bottom left side of the screen is global, not local axis. To switch on the local axis, press Shift + O on your keyboard. Blue arrow always represents the local X axis, so releasing MX moment will allow the member to spin around its longitudinal axis.
