Abstract: Natural hazards impose great distresses on many type of structures, which leads to large economic, environmental, and human losses. Large storage areas, in which large cylindrical storage tanks are used, are particularly vulnerable to certain natural events such as earthquakes, tsunami, and storms. This vulnerability can result in technological accidents (also known as Natech) such as the release of hazardous materials or the loss of valuable resources. The objective of this paper is to present a Natech-based approach for the development of fragility curves that can be used in the performance analysis and the design of storage tanks, for a large variety of tank configurations, and for various types of storage park/area setups. This is achieved through a parametric methodology that allows for specific tank modelling, instead of more traditional approaches (i.e., historical records). Furthermore, a formulation for the analysis of tank groups subjected to extreme events is presented. The model for isolated and grouped tanks, and its applications, are illustrated through several examples. This analysis is restricted to the case of ground supported, liquid-atmospheric storage tanks. Specifications for other tank geometries and operation conditions (e.g., elevated, rectangular or pressurized tanks) can be found elsewhere.
