Time-Dependent Risk Modeling - Capturing Dynamic System Change |
November 5, 2015 |
Anne Kiremidjian Current risk and resilience assessment methodologies consider the current state of structures, infrastructure, social and economic conditions. Our existing structures and infrastructure are continuously deteriorating, while the urban landscape is constantly changing and growing exponentially. In this presentation the dynamic components of risk assessment are identified and modeled as they pertain to earthquake hazards. Examples of fragility function development for deteriorating structures and incremental structural expansion are presented illustrating the increase in their respective vulnerability. Time-dependent risk forecasts for Kathmandu are used to discuss resilience options under various social and economic constraints. |
