The eco-composite wall structure consists of concrete blocks，concrete frame grids , concealed frame and so on. When entering, the obvious damage phenomena appears on the eco-composite wall, the deformation coordination between the block and the frame grid, compound wall and the outer framework is broken, which brings relatively large-difficulty to establish the elasto-plastic model of structure. The rigid frame - whole bracing model of the eco-composite wall structure in elastic-plastic stage is presented based on previous study. The correctness of models is verified by experiments. Theoretical analysis and experimental results show that the rigid frame-whole bracing model giving consideration to accuracy and efficiency is applicable to structural elastic-plastic time-history analysis under strong seismic action.
