针对强震作用下典型装配式剪力墙结构的破坏机理和薄弱环节
提出一种具有耗能减震功能的新型装配式剪力墙。采用模型试验和数值模拟相结合的方法
设计制作了4片缩尺比1∶1.54、剪跨比1.52的新型装配式剪力墙试件
并对其进行了相应的抗震性能试验
系统分析了螺栓数量、轴压比和边缘构件纵筋配筋率对试件破坏模式、滞回性能、承载能力、变形性能、刚度退化及耗能能力的影响规律。试验结果表明:各试件破坏模式与相同剪跨比的现浇剪力墙基本一致
呈弯剪型破坏;但新型装配式剪力墙具有更为优异的滞回性能和耗能能力
其在破坏点的耗能值显著高于普通现浇墙体;当螺栓数量减少时
新型装配式剪力墙承载能力无明显变化
但滞回性能降低、墙体变形加剧;轴压比或边缘构件纵筋配筋率的降低会导致剪力墙承载能力降低和极限位移增大。最后采用ABAQUS软件建立了相应试件的有限元模型
模拟结果与试验结果吻合较好
表明所建模型的正确性
能够将其应用于新型装配式剪力墙的分析之中。
Considering the failure mechanism and weaknesses of traditional fabricated shear wall structures under strong earthquakes
a new type of fabricated shear wall with functions of energy dissipation and shock absorption was proposed. On the basis of model test and numerical simulation
seismic performance tests were carried out on four specimens with scale ratio of 1∶1.54 and shear span ratio of 1.52. Further analysis was conducted to investigate the effects of bolt number
axial compression ratio
and reinforcement ratio of edge members on the seismic performance of the new fabricated shear wall
including failure modes
hysteretic performance
bearing capacity
displacement ductility
stiffness degradation
and energy dissipation capacity. Test results show that the four specimens experienced shear compression failure
which was the same as the cast-in-place shear wall with the same shear span ratio. However
the proposed shear wall had better hysteretic performance and energy dissipation capacity
and the energy dissipation capacity was higher than that of the cast-in-place shear wall at the failure point. When the number of bolts decreased
the hysteretic performance of the new fabricated shear wall decreased
the wall deformation increased
while the bearing capacity remained almost unchanged. When the axial compression ratio or reinforcement ratio of edge members decreased
the bearing capacity decreased
and the ultimate displacement increased. Finally
the finite element model of the specimens was established by ABAQUS program. Comparisons of numerical results and test results showed a good agreement
verifying the correctness of the model
which can be applied to the analysis of the new fabricated shear wall.
