Abstract:: The numerical models of the 5 ecological composite walls filled with different materials were established by finite element analysis software ABAQUS, then the nonlinear damage analysis was carried out, and the results were compared with experimental results. The damage field distribution and plastic damage behavior of 5 ecological composite wall models were studied, the damage evolution process of typical region of wall was analyzed, the idea of damagereduction design method based on the performance of ecological composite wall structure was put forward. The results show that the damaged areas of ecological composite walls are mainly concentrated in the middle layer of blocks, the junctions of ribbed beam, ribbed column and base and top of end frame;the changing laws of damage indexes of local and global are increased by the effects of accumulative deformation; global damage index provides certain theory basis for earthquake evaluation of ecological composite wall structure; block, ribbed grid and frame are three seismic fortification lines of ecological composite wall structure.
