Dual system.
Dual system.
(OP)
I am trying to hand check the structural analysis of an eight storey dual system (shear wall and moment frame) building. For the lateral load, how should I assign loads to moment frames and shear walls? I assume they will be shared by moment frames and shear walls based on their relative stiffness. Is there any easy method to figure out this distribution?

Unless it is very obvious that shear walls would resist significant portion of lateral force, I would suggest creating 3-D model to get proper load distribution.

Is this a seismic requirement only, as shin references?
RE: Dual system.
1. Force effect in the moment frame considering the relative stiffness of the shear wall and the moment frame, and
2. 25% of the total lateral force (seismic) acting on the moment frame alone.

Of course, the rest of this section has the myriad of other trivia that some code writing committee added to the "to-do" list.
