Summary: Shape memory alloys (SMAs) have attracted significant attention as potential damping device materials in recent years. This article provides a comprehensive review of the damping characteristics of SMAs and the experimental methods used to characterize their damping properties. The shape memory response and associated damping quality of Fe-based, Cu-based, and NiTi-based alloys, including their behaviors and limitations, are discussed. The review also highlights the important parameters that impact SMA damping behavior, which need to be investigated by researchers and manufacturers to address current design challenges.

Summary: This study proposes a hysteretic model that accurately predicts the behavior of shear deformation of high-damping rubber bearings (HDRB) when designing seismic isolation structures. Dynamic loading tests were performed to investigate the nonlinear characteristics of HDRB, and it was found that these characteristics strongly correlate with the shear strain experienced in the past. Furthermore, a hardening phenomenon was confirmed when shear deformation exceeded a certain level. Based on experimental results, the study evaluated and analyzed the dynamic characteristics of HDRB, including equivalent stiffness, equivalent damping ratio, and strain energy. An improved bilinear HDR model was developed to reproduce the dependence on shear deformation and hardening phenomena, and an objective parameter-setting procedure based on experimental results was proposed for modeling with minimal parameters. The proposed model corresponded with experimental results within a 10% error margin.

Summary: This study investigates the effects of thermal oxidation ageing on NBR seals, showing that it significantly impacts the rubber properties such as hardness, bulk modulus, tensile strength, and tear strength. Different ageing degrees result in distinct damage mechanisms, with the wear mechanism shifting gradually from adhesive wear to abrasive wear or fatigue and abrasive wear. Despite a decrease in average wear rate with increased ageing parameters, important mechanical properties like viscoelasticity and fracture resistance are severely reduced or lost entirely due to ageing degradation.

Summary: Rammed earth-timber joints without enlarged ends have been used for hundreds of years in rammed earth buildings. Factors such as compressive loading, embedment length, and surface roughness can affect joint performance. Joint stiffness decreases non-linearly with increasing pull-out displacement, with primary energy dissipators being high vertical compression, deformability of timber frames, and plasticity of rammed earth.

Summary: A new type of braced frame structure with a double-cylinder arc energy dissipator is proposed in this study. The seismic performance of this structure was analyzed, and the results showed that the double-cylinder arc energy dissipator could effectively dissipate seismic energy and prevent out-of-plane buckling deformation of the brace. The height, thickness, and spacing of the stiffener significantly influenced the seismic performance of the braced frame.
