Seismic safety evaluations of industrial facilities, including quantitative risk analysis(QRA) procedures, can be supported by an assessment of potential damages resulting from seismic what-if-scenarios. This contribution presents an engineering methodology for classifying the damage level of buildings subjected to seismic loading based on the assessment of discrete structural members. The degree of damage of structural members subjected to seismic loading is typically derived from numerical simulations of engineering methods. However, the extent of damage sustained by the entire building cannot be linearly extrapolated from the individual member damage. The damage level expected for the overall structure is determined from the interaction of all loadbearing members and their individual contribution to the overall load bearing system. To quantify this individual contribution, a structural member damage index is defined, which forms the basis for the damage assessment of superordinate structural systems by use of damage curves. These damage curves were obtained for various types of structural systems common in industrial facilities. While the presented curves were derived for other extreme loading types and hence different structural failure modes, it is shown how the methodology is transferable to failure modes relevant for seismic evaluation of industrial engineering structures.
