Special Concrete Shear Wall on Special Concrete Moment Frame
Special Concrete Shear Wall on Special Concrete Moment Frame
(OP)
Is there any code limitation (IBC 2003) that would prevent me from designing a 5 story building with the ground floor being special concrete moment frames, and the upper floors beaing special concrete shear walls. FYI, would be seismic design category D
I'm aware of all the overstrength requirements for elements supporting discontinues shear walls, etc.
Just want to make sure the code will let me use this system.

RE: Special Concrete Shear Wall on Special Concrete Moment Frame
Another code provision that would affect your design is ACI 318-02 Section 21.4.4.5. Where you have a shearwall being discontinued atop a column, this section requires you to add transverse reinforcement in the column below and to extend transverse reinforcement up into the wall for a distance at least equal to the development length of the column rebar.

Assuming you are not greater than 65 feet - you would have to include dynamic characteristics in your Equivalent lateral-force procedure.
