Abstract:In order to study the seismic performance of recycled aggregate concrete-filled double steel plate composite shear walls, the finite element software ABAQUS was used for model verification and analysis on the basis of existing tests. The research contents include replacement rate of recycled coarse aggregate, distance -thickness ratio, axial compression ratio and connector form. The results show that: (1) With the increase of recycled coarse aggregate replacement rate, the flexural capacity, shear capacity and initial lateral stiffness of the specimens have different degrees of deterioration; (2) when the axial compression ratio is 0~0.5, the bearing capacity decreases and the initial stiffness increases with the increase of it; (3) for the recycled concrete shear wall specimens with shear span ratio of 1.5 (replacement ratio of recycled coarse aggregate is 100%), the shear bearing capacity decreases with the increase of distance -thickness ratio; (4) the forms of connectors have little effect on the early bearing capacity and stiffness, but have a great influence on the shear and bending bearing capacity of the later loading period.
