According to the special forms and mechanical behavior of frame-composite walls, displacement calculation method for frame-composite walls under horizontal loads is proposed in this paper. The model of frames and composite walls in parallel is adopted for considering working together of them. Cracking of filling blocks at middle and end elastic stages is taken into account. Based on material and structure mechanics theories, the displacement calculation method of frame-composite walls is derived from that of frame structures. The calculation results of the proposed method agree well with the test results of multi-grid composite wall with edge frame columns reinforced by steel. The displacement calculation method of frame-composite walls is compatible with that of frames and that of RC shear walls. The shear deformation of the frame-composite wall contributes most to the whole deformation. And the lateral displacement curves of middle to high-rise frame-composite wall structures are characterized by flexure-shear deformation. The proposed displacement calculation method for frame-composite wall structures can be used as a reference for structural design
