When we are assigning shear wall to a model whether or not the self weight of shear wall is accounted for by the etabs in calculating seismic mass and/or the equivalent lateral load by etabs.
 
Yes. All elements modeled are taken into account for weight. Forces are then distributed to the diaphragms (half and half)

 

If you wall is meshed between story to model adequatly the flexibility of the wall then the mass of the meshed element between two story is not accounted in lateral mass..

I think this is a serious bug.

I have beed able to reproduce this bug on all my project.

Be cautious and always verify everything !
 
Yes, PicoStruc is right.

However, if you manually mesh the walls, then the mass is appropriately captured. The bug seems to be only in the automesh option for walls.
