In order to promote the application of aeolian sand resources in steel-concrete composite shear wall, a kind of aeolian sand concrete shear walls with concrete filled steel tube (CFST) columns and concealed bracings is proposed in this paper. The shear wall is composed of aeolian sand concrete, steel bar, steel tube and steel plate. Through the low cyclic loading test of three aeolian sand concrete shear walls with CFST columns specimens and aeolian sand concrete shear walls with CFST columns and concealed bracings specimens, the influence mechanism of setting concealed bracing on the seismic performance of the specimens was revealed. The results show that under the same replacement rate of aeolian sand, the setting of concealed bracing can significantly improve the load-carrying capacity, ductility, stiffness degradation behavior and energy dissipation capacity of the specimens. In addition, the calculation models of normal section bearing capacity for aeolian sand concrete shear walls with CFST columns and aeolian sand concrete shear walls with CFST columns and concealed bracings are established. The test results are in good agreement with the calculation results.
