“…Additionally, metal dampers with the benefits of low cost, convenience to obtain, and excellent energy dissipation are the most widely used, which can be divided into flexural-yield-type, shear-yield-type, and tension-yield-type metal dampers. Owing to the simple design and excellent energy-dissipating capacity of the ADAS [17] and Ushaped dampers [18], the flexural-yield-type metal dampers [19][20][21][22][23] developed lately are mostly derivatives of the aforementioned dampers and are often designed with new metal materials [24]. These have mainly been successfully applied in the frame structure [19,20], shear wall structure [21,22], self-centering concrete wall structure [23], and base-isolated structure [24,25] to improve the seismic resilience of a structure.…”

Although the stable energy dissipation can be found in the flexural-yield-type metal dampers, the stiffness and bearing capacity of this metal damper are relatively lower considering the obvious out-of-plane deformation behavior.…”

To investigate the hysteretic behavior of an X-shaped metal damper (XMD) with an oblique angle, cyclic loading tests were carried out on nine specimens, including two XMDs without buckling-restrained devices, four XMDs with stiffening ribs, and three XMDs with cover plates as references. The test results showed that the oblique angle could effectively increase the stiffness, strength, and energy dissipation of the XMD. When the oblique angle of an XMD with stiffening ribs increased from 0° to 30° at the applied displacement of 8.4 mm, the mean strengths and cumulative energy dissipation of specimens increased by about 80.77% and 80.57%, respectively. Although asymmetric hysteretic loops were also observed in specimens with an oblique angle and buckling-restrained devices, stable hysteretic curves were obtained. This indicated that the stiffening ribs and cover plates can effectively constrain the buckling behavior of XMDs. Additionally, the mean strengths of specimens with stiffening ribs were a little higher than those of specimens with cover plates. Subsequently, the finite element analysis models of the XMDs were proposed, in which the metal plasticity model considering isotropic and kinematical hardening was used to model the material properties of steel, and the simulation results matched well with the test results. Finally, the theoretical calculation method was proposed to predict the elastic stiffness of specimens, and the theoretical elastic stiffness matched well with the test results.
