This paper describes the experimental results of dynamic tests used a 1-storey steel building model with pipe-type-damper. The building model was designed to have the same first natural frequency as the detached houses, which is the external size, 1.4m×0.9m×2.35m and the total mass, 760kg. The first natural frequency of building model is 3.92Hz, and the damping ratio is 0.25%. The two tests used the building model were performed; (1) is free vibration test, (2) is traffic-induced vibration test. The results of free vibration tests showed that the pipe-type-damper could give building model the damping. Also, the damping ratio of the building model are almost the same as the design value; the experimental value is 7.53%, and the design value is 8.19%. The results of traffic-induced vibration tests showed that the pipe-type-damper was able to reduce the acceleration and displacement of building model against minute vibration.
