It is important to know initial performance of the structure in urgent measure on damages due to earthquakes and the control of maintenance. In this research, the vibration test at the same time construction step of the structure to grasp an initial performance of the structure to use a continuous Arch-culvert structure that used precast members was executed, and the natural frequency of the structure was understood. The reference value to evaluate the performance of each material that secured safety was examined by confirming the validity of the design technique of the structure by using the result, and forecasting the change of the value by the analysis in an initial value to receive damage due to the earthquake etc. while the structure was using it in being do the maintenance management of the structure in the future.
