In recent years, there stories houses are built increasingly in the urban areas to obtain wide living space in a narrow land area. These houses are subjected to numerous vibration problems caused by the traffic flow which is increasing day by day. These problems depend on the vibration characteristic of the houses and the bases. In general, there are three ways one can these problems : (1) A measure at the source of excitation : to regulate traffic. (2) Ameasure at the route of vibration : to improve the characteristic of the base i.e., the vibration isolation. (3) A measure at the houses : to modify the construction for vibration suppression. To suppress the vibration, generally one use (i) Active mass damper (AMD) (ii) Tuned mass damper (TMD). AMD devices use active feedback control scheme and very expensive to implement. TMD is e passive device. In TMD, a large mass is used which is placed on the top floor of the building. This is not good from the safety point of view. In this report, a new device called pendulum tuned mass damper (PTMD) is proposed to reduce the vibration. This device acts on the principle of lever mechanism and thus 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 and experimental studies.
