This research project has conducted a feasibility study on the net web monitoring system for seismic security including structural capacity of building and indoor space safety for individuals. It is a goal of the high priority of earthquake protection planning that it does not kill and not injure the human in earthquakes ; for the sake we have designed this system applicable to offer a lot of disaster prevention information about structural diagnosis of buildings, damage evaluation of building structures against scenario earthquakes, indoor space safety check and human damage evaluation of injury and death rate per household. We have discussed the bland new diagnosis methods from various points of view as structural engineering, material engineering, house planning and disaster medical science. First, the study on structural diagnosis discussed the improvement of diagnosis method based on the microtremors of building, and obtained two results. One is to propose a primary evaluation met … More hod capable of simple and handy measurement for seismic capacity of buildings by using a Laser Doppler Vibrometer by which can obtain the high resolution records of microtremors. The second result is to verify the usability of a new technology through the chaos analysis of microtremors. Chaos is an index showing the complexity of the vibration of building. Add to the predominant period of building, the diagnosis becomes more refined method by paying attention to some indices as complexity of vibration. Second, we developed a diagnostic system aimed at seismic indoor risk reduction based on the evaluation algorithm of seismic casualty risk potential in dwelling space and of evacuation risk to outdoors. Third, we discussed Damage Index Function by which damage state of individual building can be estimated, and proposed the method for deducing the functions with structural parameter of the load-carrying capacity for buildings, that means the informative process from diagnosis results to disaster prevention information for individuals. Fourth, we proposed the death rate function with the parameters of them in order to precisely estimate casualties per house. Proposed functions are also applicable for the effective seismic reinforcement plan for the house to decrease the casualties in the municipality or governmental unit. Finally, we discussed a centralized data surveillance system. Less
