Abstract：Multi-grid composite wall-shear wall structure is a new type resistant structure consisting of composite walls and shear-walls which can effectively solve some disadvantageous problems about multi-grid structure, such as building height and application range were constrained in highly seismic area. Displacement calculating method for the structure subjected to horizontal loads was proposed. Based on Timoshenko beam theory, the composite wall was treated as shear-flexural type cantilever wall, and the displacement differential equation was established by the continuous approach, then the deformation analytical solutions were derived. The examples show that frame-shear structure can be regarded as one of special forms of composite wall-shear wall structure, and the whole lateral displacement curve of the structure express shear-flexural type characteristic which shear deformation should not be ignored. The findings provide a theoretical fundamental to study and internal force calculating method anti-seismic design further.
