Structural dynamic characteristics are obtained by analysing responses of seismic acceleration measuring system obligatorily installed in public structures. Emergency structural safety estimation using these data supports decision making of a structure manager when an earthquake or a strong vibration happens. And proper standards for structural safety are suggested by cumulative statistical analysis. For these reasons, it is necessary that comprehensive analysis and management system indicates analysis results based on GIS(Geographic Information System). This system is developed with comprehensive analysis algorithms and data processing procedures. Various information through the system is served for structural safety management.
