Vibration Control of a Long-span Floor in a Large Station Room Considering Human Comfort
摘要
Abstract
In recent years, the large station rooms were built all around the country, and most of the floors in these structures have the properties of long-span, light weight and low damping. Based on the consideration of human comfort, these floors are analyzed on its vibration serviceability. Firstly, a finite element model of a large station room is established, and the vibration properties of the long-span floors in this structure are studied. Secondly, the vibration serviceability of the floor structure caused by some disadvantageous cases is analyzed. Finally, a design method with multiple tuned mass dampers (MTMD) system is presented. The study results show that the MTMD system can control the vertical vibration of the longspan floor effectively, and the average attenuation rate under various working conditions is about 34% and the human comfort requirement under pedestrian excitation is satisfied.关键词
