In order to study the seismic performance of the new adobe wall structural system. A one-story foot-scale new adobe wall building test model with plan size of 3.6 m×3.0 m and storey height of 2.45 m was designed and fabricated for the shaking table test, and El Centro waves and Yunnan Ludian (LD) waves were selected for the test to carry out unidirectional loading of seismic waves in the X and Y directions, respectively, and the test model was measured to be under the peak acceleration of 0.10、0.22、0.40、0.62、0.90 g, the spectral characteristics, acceleration response, displacement response, torsion response, and strain response of the dark column reinforcement were measured. The results show that: the model is only slightly damaged in the exceeding 9 degree rarefied intensity, and there is no obvious cracking and damage phenomenon under other seismic excitations. With the increase of seismic excitation, there is no obvious change in the self-resonance frequency of the model, and the acceleration amplification coefficient gradually decreases, with the maximum amplification coefficient of 3.666 at the roof. The angle of the interstorey displacement reaches the maximum of 1/399 when the peak acceleration is 0.62 g. The overall structural torsion is 1.599 at the peak acceleration of 0.62 g, and the displacement angle of 0.62 g reaches the maximum of 1/399. Because of the basic homogeneous symmetry, the structural torsion is 0.666 at the roof. Because the model is basically homogeneous and symmetric, the overall torsional effect of the structure is not obvious. The strain value of the steel reinforcement of the dark columns increases gradually with the increase of the seismic excitation, but the strain value of the steel reinforcement is small and the performance of the steel reinforcement fails to give full play. In summary, the new adobe wall model has good seismic performance, and the study provides a test basis for expanding the application range of adobe buildings.
