中文摘要：
为研究一种新型的带可更换墙脚构件的剪力墙的抗震性能，完成一组5片试件并进行低周反复加载试验研究。从试件的试验现象、抗侧承载力、变形能力、阻尼变化等方面分析对比普通剪力墙和新型剪力墙的抗震性能上的差别，并研究轴压比和高宽比对于新型剪力墙抗震性能的影响。研究结果表明：新型剪力墙比普通剪力墙水平承载力略降低，变形能力是普通剪力墙的2倍；新型剪力墙的耗能能力在屈服点时明显比普通墙高，加载后期耗能能力取决于可更换构件本身的变形能力；新型剪力墙的轴压比越大，水平承载力越大，骨架曲线上各关键点的位移出现的越早，平均耗能能力越强。同时，高宽比大的新型剪力墙，其水平承载力较低，变形能力更好，平均耗能能力较强。
英文摘要：
In order to study the seismic performance of one new designed RC shear wall with replaceable foot parts, 5 pieces of test specimens were produced to conduct the quasi-static cyclic tests. The differences between the new designed shear wall and the conventional shear wall in the crack pattern, lateral bearing capacity, deformation capacity, and damping parameter were presented. The influence of axial load ratio and aspect ratio on the seismic performance of the new designed wall was also analyzed. The results reveal that the lateral bearing capacity of new shear wall is lower than that of the conventional one, but the deformation capacity is two times of the conventional wall. The damping parameter of the new shear wall is higher than that of the other at the yielding point, and the increase of the damping parameter depends on the deformation capacity of the replaceable member. With the increase of the axial load ratio applied on the top of the walls, the lateral bearing force of the new shear wall becomes higher with a smaller displacement of each keypoint on the force-displacement skeleton curve and a larger average energy-dissipating capacity. Meanwhile, the new designed wall whose aspect ratio is larger gains a lower lateral bearing force with better deformation capacity and energy-dissipating capacity.
