    摘要:

    为了解砌体墙破坏过程中的转动现象及转动变形对砌体墙抗震性能的影响,对普通砌体墙、设置构造柱砌体墙、加固砌体墙等在试验过程中的转动现象进行提炼,综述不同试件设计、受力条件、加固方式等因素下转动变形对砌体墙破坏模式的影响,探讨转动变形对砌体墙抗震性能的影响规律。结果表明:在砌体墙受力过程中,转动现象普遍存在,甚至出现转动变形控制的破坏现象;转动变形降低了砌体墙承载力及等效抗侧刚度,发生转动破坏时砌体墙变形能力有所提高。目前,有关砌体墙抗震试验方面的文献资料普遍缺乏关于转动现象的描述,但这并不代表没有出现转动变形,建议后续相关研究中对砌体墙转动变形现象及其对抗震性能的影响予以重视。

    Abstract:

    In order to understand the rotation phenomenon in the failure process of masonry wall and the influence of rotation deformation on the seismic performance of masonry wall, rotation of ordinary masonry wall, masonry wall with constructional column and reinforced masonry wall are extracted, and the rotation deformation under different specimen designs, stress conditions, reinforcement methods and other factors are summarized The influence of rotational deformation on the seismic performance of masonry wall is discussed. The results show that: rotation is common in the stress process of masonry wall, and even appears the failure phenomenon of rotation deformation control; rotation deformation reduces the bearing capacity and equivalent lateral stiffness of masonry wall, and the wall deformation capacity is improved when rotation failure occurs. At present, the literature of masonry wall seismic test generally lacks description of rotation phenomenon, but it is not without rotation deformation. In the subsequent research work, it is suggested to pay attention to the rotation deformation phenomenon of masonry wall and its impact on seismic performance.
