Abstract: In order to study the influence of infill walls on the seismic performance of infilled in frame structures，the concrete frame，the wall with lightweight aggregate concrete block infilled frame wall， and the multi-story infilled-frame wall were analyzed by the ABAQUS. The structure's failure mode， hysteresis curve， skeleton curve， stiffness degradation performance，and energy dissipation capacity were compared. The results show that the lightweight aggregate concrete block infilled-frame wall has better mechanical performance. Adding an infilled wall inhances the structure's lateral force deformation resistance，and energy dissipation capacity. It improves the bending and shear performance of the multi-story frame structure. The wall with lightweight aggregate concrete block infilled frame is green， environmentally friendly， resilient， and has good seismic performance.

Key words: infilled-frame wall, low cyclic loading, seismic performance, numerical analysis
