The past two decades have witnessed the adverse effects of low-frequency components of severe earthquakes in low-frequency structures. The development of displacement control technologies for the seismic protection of low-frequency structures has been identified as a growing challenge in earthquake engineering. Related studies have suggested that rate-independent linear damping (RILD) could be a viable option for reducing excessive displacements in low-frequency structures. However, previous studies on RILD systems have not extensively investigated their input energy during an earthquake. The main objective of this study is to examine the earthquake input energy of low-frequency structures equipped with a passive rate-independent damping device. The differences in the input energy of the linear viscous damping (LVD) and RILD systems are investigated, based on real-time hybrid simulations and frequency-domain analysis.

被动率无关阻尼装置低频结构地震输入能量试验研究

近二十年来，我们见证了强震低频分量对低频结构的不利影响。开发用于低频结构抗震的位移控制技术已被认为是地震工程中日益严峻的挑战。相关研究表明，与速率无关的线性阻尼 (RILD) 可能是减少低频结构中过度位移的可行选择。然而，以前对 RILD 系统的研究并没有广泛研究它们在地震期间的输入能量。本研究的主要目的是检查配备被动速率无关阻尼装置的低频结构的地震输入能量。
