中文摘要:
      为研究双钢板-再生混凝土组合剪力墙的抗震性能,在已有试验的基础上,使用有限元软件ABAQUS进行模型验证和分析,研究内容包括再生粗骨料取代率、距厚比、轴压比以及连接件形式。结果表明:(1)随再生粗骨料取代率的增加,试件抗弯承载力、抗剪承载力、初始抗侧刚度均出现不同程度的劣化;(2)当轴压比为0~0.5时,试件承载力随轴压比增大而减小,初始刚度随轴压比增大而增大;(3)剪跨比为1.5的再生混凝土(再生粗骨料取代率为100%)剪力墙试件,抗剪承载力随距厚比的增大而下降;(4)连接件形式对试件的早期承载力和刚度影响较小,但对加载后期的抗剪承载力和抗弯承载力影响较大。
英文摘要:
      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.
