Abstract: Integrate the insulation material into the double-faced superimposed sandwich shear wall, a double-facedsuperimposed sandwich insulation shear wall structure suitable for low-rise buildings was designed. This structure has theadvantages of component production and construction, and has application and promotion prospects. In order to study theseismic performance of the system, a full-scale two-story two-bay structure model was subjected to seismic shaking table testto analyze the damage accumulation process of the structure under different seismic conditions, and to study the dynamiccharacteristics of the text model and the change law of seismic response. Tests have shown that the structure remainsbasically intact under the action of 7-degree frequent and 7-degree fortified earthquakes. Under the action of 7-degree, 8-degree, and 9-degree rare earthquakes, the natural frequency of the text model drops to a certain extent, and theappearance cracks appear and continue to develop with the increase of seismic action, but the structure has no obviousdamage, and the basic performance is stable. The text model can meet the three-level fortification requirements of thecurrent seismic code, and has certain application advantages in low-rise buildings.
