Causal hysteretic damping, extended Rayleigh damping, and uniform damping are models with frequency-independent damping ratios over a wide frequency range. However, there are many unclear points about its applicability to inelastic problems. Therefore, in this study, in order to compare the vibration characteristics of these damping models, analyses were performed by inputting white noise to multiple 1-degree-of-freedom model with different natural frequencies. As a result, it was confirmed that these damping models are frequency-independent even under inelastic conditions. Furthermore, causal hysteretic damping and extended Rayleigh damping can compute in the same computation time as conventional Rayleigh damping.
