Modeling of Dual System Structure in ETABS

[BONILL]

I have a 7 story concrete building. For lateral design, the structure is composed of a dual system with special moment frames with special reinforced concrete shear walls. The moment frames must be capable of resisting at least 25% of prescribed seismic forces. In ETABS I should model my structure without the shearwalls and apply only 25% of the lateral load in each floor. However, some of my beams are supported at their ends by the same shearwalls I am removing. What should I do in this situation?
