In this report, a new vibration control device called pendulum tuned mass damper (PTMD) is proposed to reduce a ordinal house vibration. In recent years, three stories houses are built increasingly in the urban areas to obtain wide living space in a narrow land area. These houses are subjected to a problem caused by the traffic vibration, because a dominant frequency of the traffic vibration is coincident with the natural frequency of these houses. Although tuned mass dampers (TMD) are considered to solve the problem, it needs to prepare a large mass on the top floor of these houses in order to obtain effective vibration reduction. It seems to invite the dangerous situation under the large earthquakes. The proposed PTMD acts on the principle of lever mechanism and this requires a small tuned mass. This is also cost effective and can be placed between the first and second floor. The vibration control results are verified through simulation studies.
