This paper discusses the vibration test of the 256m-height high-rise building built on the filled ground. This building is made by the steel structure, and it has a very slender proportion. We measured the natural period and the damping factor of the building. The measured natural period in the transversal direction is 1.09 times as the calculated one. We suppose that the sway and rocking motion of the around has a great influence in the aforementioned condition. The damping factor in this direction is 0.72%. Otherwise, the natural period in the longitudinal direction is 0.91 times as the calculated one. The damping factor is 2.91%. This condition is influenced by the finish of the building.
