    摘要:

    设计了1个带有传统连梁的双肢剪力墙试件和1个带有可更换连梁保险丝的新型双肢剪力墙试件,通过低周反复加载试验对2个试件进行了抗震性能对比研究.研究表明,带有可更换连梁的新型剪力墙和传统剪力墙具有相同的承载力,其等效黏滞阻尼大于传统剪力墙,强度退化小,而且新型剪力墙能够将连梁的受损位置集中在保险丝,便于震后更换.

    Abstract:

    A conventional coupled shear wall specimen and a new coupled shear wall specimen with replaceable coupling beams were designed and tested by low cyclic loading tests. The seismic performance of two types of shear walls were studied and compared. The results show that the two specimens have similar bearing capacity. In addition, the new shear wall possesses larger equivalent viscous damping and displays less strength degradation. Moreover, the replaceable coupling beam of new shear wall make the structural damage concentrate in the fuses, while the other parts of replaceable coupling beams keep intact, which is beneficial to replace the damaged fuse after the earthquake easily.
