Net Web Monitoring for Seismic Security Covering from Structural Capacity of Dwelling to Indoor Space Safety

本课题对建筑结构承载力和个人室内空间安全的地震安全监测系统进行了可行性研究。在地震中不造成人员伤亡是防震规划的一个高度优先的目标；为此，我们设计了该系统，适用于提供建筑结构诊断、建筑结构对情景地震的损伤评估、室内空间安全检查以及每户伤亡人数的人身伤害评估等大量防灾信息。本文从结构工程、材料工程、房屋规划和灾害医学等多个角度探讨了新的诊断方法。首先，在结构诊断研究方面，探讨了基于建筑微震的诊断方法的改进，得到了两个结果。一是提出了一种初步的评价方法，可以用激光多普勒测振仪简单方便地测量建筑物的抗震能力，从而获得高分辨率的微震记录。第二个结果是通过微震的混沌分析来验证新技术的可用性。混沌是反映建筑物振动复杂性的指标。加上建筑的优势期，通过对振动复杂性等指标的关注，使诊断更加精细化。其次，基于居住空间地震伤亡风险潜力评估算法和室外疏散风险评估算法，开发了室内地震风险降低诊断系统。第三，讨论了评估个体建筑损伤状态的损伤指标函数，提出了基于建筑物承载能力结构参数的函数推导方法，即从诊断结果到个体防灾信息的信息过程。第四，我们提出了带有这些参数的死亡率函数，以便准确估计每户房屋的伤亡人数。建议的功能也适用于有效的房屋抗震加固方案，以减少市政或政府单位的伤亡。最后，我们讨论了一个集中的数据监控系统。少

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
