Urban-Scale Earthquake Risk Management Utilizing Structural Health Monitoring Technology
With the adoption of the Sendai Framework for Disaster Risk Reduction, an important step was taken towards resilient cities. For cities under seismic risk, real-time data is needed for early diagnosis of the structural risk, creating seismic risk and shake maps, and evaluating the situation rapidly for disaster coordination and achieving rapid comeback to the normal flow of life. Structural Health Monitoring (SHM) is the technological decision support system that helps to monitor, analyze and report the structural integrity and the damage condition of civil engineering structures with the help of sensors. Innovative part of the SHM arises from the dynamic identification of a structure under ambient vibration in real-time, using ultra-sensitive accelerometers. A rapid change in the characteristic response of the building is usually accepted to be an indicator of damage, revealing the loss of structural integrity and stiffness. It is possible to compare the dynamic response of the building just before and after an earthquake to form the most rapid data-driven approach to support the decision-makers. Even though the SHM solution is adopted for high-rise buildings mostly in recent building codes, generally the greater number of mid-rise buildings lies in the higher risk group. It is feasible to monitor these buildings even with one to three triaxial accelerometers, cost-effectively. With the effective utilization of SHM technologies, it is possible to manage the disaster in a data-driven manner. In this study, a three-component technology-based, holistic method is proposed, to increase urban resilience and effectiveness in earthquake risk management.
