Abstract
In this paper, some results of vibration measurements and analyses of the existing RC arena which passed through 25 years from the construction are shown. From the obtained results, the identification of the vibration characteristics become possible by vibration measurements and 3D-FEM analyses, and the response level of the shell roof is quantitatively predictable from the earthquake response analysis. It will be applicable to the direct estimation of the seismic capacity of the structural members and nonstructural members such as hung ceilings and suspended luminaires.
