Amplification characteristics of the horizontal vibration on road traffic vibration to wooden house

Verification measurements were conducted to estimate amplification by road traffic vibration in the building through field measurements of 32 wooden houses and verification measurements of experimental buildings. "Negative correlation" that larger input vibration decreases the amplification level was recognized. It was revealed that higher vibrational components do not transmit to the building, which leads lower amplification level, and larger wall quantity increases negative correlation in the specific frequency band of the building. However, the traffic vibration is a minute transformation, and it is thought that it is difficult to control the amplification level directly by the amount of the wall.
