Risk Assessment Methodology

Recent events outlined the relevance of the interactions between industrial and natural hazards (NaTech) particularly for what concerns seismic risk. EU regulation, namely Directive 2012/18/EU, explicitly requires risk analysis for NaTech events. The development of a risk assessment methodology for major hazard industrial plants allows the individuation of the critical elements of a plant in seismic-prone areas. The following implementation of smart technologies (sensors, actuators, innovative systems for seismic protection) to the critical elements allows for a relevant reduction of major hazards and related consequences.

Abstract Recent events outlined the relevance of the interactions between industrial and natural hazards (NATECH) particularly for that concern seismic risk. EU regulation, namely Directive 2012/18/EU, among its new elements explicitly requires the analysis of NATECH hazards. The development of a risk analysis methodology for major hazard industrial plants allows the individuation of critical elements of the plants with regard to seismic actions. The following implementation of smart technologies (sensors, actuators, innovative systems for seismic protection) to the critical elements allows a relevant reduction of major hazards and related consequences.

This paper deals with state of the art risk and resilience calculations for industrial plants. Resilience is a top priority issue on the agenda of societies due to climate change and the all-time demand for human life safety and financial robustness. Industrial plants are highly complex systems containing a considerable number of equipment such as steel storage tanks, pipe rack-piping systems, and other installations. Loss Of Containment (LOC) scenarios triggered by past earthquakes due to failure on critical components were followed by severe repercussions on the community, long recovery times and great economic losses. Hence, facility planners and emergency managers should be aware of possible seismic damages and should have already established recovery plans to maximize the resilience and minimize the losses. Seismic risk assessment is the first step of resilience calculations, as it establishes possible damage scenarios. In order to have an accurate risk analysis, the plant equipment vulnerability must be assessed; this is made feasible either from fragility databases in the literature that refer to customized equipment or through numerical calculations. Two different approaches to fragility assessment will be discussed in this paper: (i) code-based Fragility Curves (FCs); and (ii) fragility curves based on numerical models. A carbon black process plant is used as a case study in order to display the influence of various fragility curve realizations taking their effects on risk and resilience calculations into account. Additionally, a new way of representing the total resilience of industrial installations is proposed. More precisely, all possible scenarios will be endowed with their weighted recovery curves (according to their probability of occurrence) and summed together. The result is a concise graph that can help stakeholders to identify critical plant equipment and make decisions on seismic mitigation strategies for plant safety and efficiency. Finally, possible mitigation strategies, like structural health monitoring and metamaterial-based seismic shields are addressed, in order to show how future developments may enhance plant resilience. The work presented hereafter represents a highly condensed application of the research done during the XP-RESILIENCE project, while more detailed information is available on the project website https://r.unitn.it/en/dicam/xp-resilience.

Seismic Resilience

Cultural heritage artifacts and buildings are under a constant thread of destruction during devastating earthquakes. Any intervention should be such that it neither violates their form nor changes drastically their structural behavior and should be reversible. In addition, the materials to be used must be compatible with the ones the monument is constructed of. Traditional seismic retrofitting techniques have the disadvantage that most of them violate the above conditions. An alternative approach is the use of innovative seismic-protection systems to enhance the seismic resilience of cultural heritage against the effects of earthquakes, which is reported in this chapter. The potential of seismic-isolation strategy to mitigate the seismic risk of museum artifacts will be first exploited. Subsequently, the state of the art of the use of energy-dissipation devices, such as viscous dampers and shape memory alloys, as well as innovative materials such as FRPs, for the protection of monuments and historic structures will be presented.

The material discusses the methods of seismic support of buildings and structures. Seismic protection measures can significantly reduce economic costs. With appropriate design, seismic isolation and seismic protection systems for foundations and buildings as a whole are capable of increasing the safety of the structure, reliability of equipment, comfort for the population, and most importantly, there is no need to carry out recovery work after strong earthquakes.
