Abstract
The purpose of this study dynamic make a study about dynamic characteristic of long-span floor system based on segmented PC method. In this study, half scale experimental model based on similitude law that applied segmented PC method proposed from previous studies was mocked up, and then dynamic characteristics of experimental model were found by experimental modal analysis and modeling method for dynamic analysis was modified by comparing the results of the experiment and analysis about dynamic characteristic. In conclusion, this study find out the dynamic characteristics (natural frequency, mode shape, transfer function) of floor structural system appling segmented PC method using the modal analysis by experimental method and program analysis method about long span structure and general structure in micro-vibration facilities. Also, long-span floor system based on segmented PC method could be verified to get vibration performance of similar or more level compared with the existing structure less than 17m span.
