this study proposes a new external-shearing and internal-framing structure, and introduces the merits and application scenarios of this new structure. With a one-staircase six-house pagoda-style residential building as the study case, we tested mechanical and seismic indicators of the proposed new structure, including the floor rigidity, the shear bearing capacity, the shear-weight ratio, the floor displacement ratio and the floor displacement angle, under different degrees of seismic fortification intensity. The test result shows that the new external-shearing and nternal-framing structure has good mechanical performance when applied to pagoda-style residential buildings, the structural control indicators meet the standards and the structure can be widely used in buildings below 33 floors with a degree of seismic fortification intensity ranging from 6 to 7.
