Comparing the Effectiveness of Friction Damper and Tuned Mass Damper Using Numerical Simulation

摘要

The purpose of this study is to evaluate and compare the effectiveness of friction dampers and tuned mass dampers (TMD) using numerical simulations. Wind and earthquake loads are simulated on a 15-story model building structure in which a friction damper and/or a TMD are installed. The idealized one-dimensional structure with a friction damper at each story and/or a TMD at the top of the building is subjected to a simulated load, and the displacement and acceleration responses of the structure are measured. The outcomes show that a TMD is more useful to control the vibration of the building from a wind load and a friction damper is more suitable for loads created by large accelerations such as those found during seismic events. This study provides verification on the performance of friction dampers and TMDs according to each of the two load types, wind and earthquake, through numerical simulations.
