ETAB Live Load Redcution

In ETAB, I defined Live load as reducible live load. I know it reduces live load for column design. But my question is does the live load get reduced for beam and joist design as well?
Because I don't want to recduce live load for beam and girder design- is there a way in ETAB so that it reduces ony for columns and not for beams and other elements?

Any help appreciated.

Yes, by choosing axial force option only. In the live load reduction menu under preferences, choose axial force only and it will reduce only that.
 
This option is ok for column design.But while you design beams and girders,it reduces the live load.
But I want to design beams and girder on the same model but without reducing live load.So far I used to design beams and girder clicking the option " No live load reduction" and while designing columns click the option "reduce per ASCE 7" and choosing the axial force option as you mentioned above.
I am wondering how other people are designing and if there is an efficient way to do it.

Thanks
 
Live load reduction can be chosen only for axial forces. It won't reduce any moments in beams. I don't know what you mean!
 
I also got reply from another post. They are recommending to overwrite the LL reduction factor =1.0 for beams and girders.And selecting the axial force only option as Slickdeals mentioned above for application to columns.

Itsolved the problem.

thanks for everyone.
 
One more question..
if i am not wrong, even if i define live load as simple live load (not reducable live) live load reduction will be applied by etabs.. rite/?
 
ETABS does not reduce Live load unless it is assigned as reducible live.
