Vibration Control of Structures with Initially Accelerated Passive Tuned Mass Dampers under Near‐Fault Earthquake Excitation
Abstract: This article deals with the applicability of passive tuned mass damper (PTMD) for reducing the dynamic responses of structures under near‐fault earthquake excitations. Three types of pulse‐like time functions are employed to simulate the near‐fault ground motion. The vibration control effectiveness of PTMDs is extensively investigated through the comparisons of response spectrum and response time histories of a structure with and without PTMDs. To suppress structural peak responses, an initial velocity is applied to the PTMD to accelerate its motion. Numerical studies show that the more cycles of a pulse are contained in the ground motion, the more useful a PTMD becomes in reducing the peak structural responses.
