A Study of Countermeasures against Road Traffic Vibration for 3-stories Houses

To grasp the application range and the effect of countermeasure for 3-stories houses in horizontal direction against the road traffic vibration, we did a dynamic analysis using the mass point model.By the parameter analysis result, we found that the effect of countermeasure depended on the combination of the house peculiar frequency and excelling frequency of the ground.When the TMD about 2% mass ratio is setting, in a lot of cases, it is possible to reduce amplification of vibration level about 2-7 dB.It found that the house vibration sometimes can be reduced about 10dB when the horizontal direction stiffness is raising twice.It is possible to say that the simulation by dynamic analysis is important to estimate for the effect of countermeasure in horizontal direction against the road traffic vibration from these results.
