Knowledge and Data Integration for Modeling of Problems of Risk due to Natural and Man-Made Hazards

It is necessary to develop continually efficient methodologies and techniques for moderating risks to be within acceptable limits. After a brief background about risk analysis, a comprehensive view is presented about the methodologies and techniques for the same. Briefly discussed are the steps such as scope definition, hazard identification, knowledge integration, risk estimation, and computation of risk and its understanding including the role of qualitative and quantitative aspects of modeling for analyzing risk. Windstorm-induced damage due to natural hazards is highlighted. A case study on estimation of the roof damage in overall risk analysis of a roof structure against damage due to cyclonic winds is used for demonstrating knowledge and data integration.
