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.
