“…This model has been implemented in the OpenSees [90], a finite element-based open-source software developed to perform structural and geotechnical seismic analyses. Thus, several authors [4], [8], [14], [49], [57], [59], [63]- [65], [69], [71], [83], [91], used this one-dimensional model to simulate different types of structures, mainly for dynamic analysis of corroded RC structures.…”

The evaluation of service conditions of concrete structures has still been carried out through implicit knowledge based on the expertise and knowledge of inspectors, who classify structures based on subjective criteria. The main degradation mechanism of reinforced and prestressed concrete structures is the corrosion of steel reinforcements, with expressive maintenance and repair costs. The phenomenon of corrosion in concrete structures has a complex behavior and presents several uncertainties, and deterministic analyzes can produce very conservative responses, which can unnecessarily increase maintenance costs, thus justifying probabilistic approaches. This article then presents a systematic literature review of articles that address the evaluation of concrete structures under reinforcement corrosion using a probabilistic approach. In this regard, 94 journal articles obtained through an appropriate review protocol were reviewed. Thus, the summary of the main proposed methodologies was carried out, as well as the identification of research gaps on the subject.

“…Several studies [61], [65], [69], [71], [83], [91], [100]- [103] evaluate the performance of corroded RC structures through seismic fragility analysis, where seismic performance is measured, by computing the probability of failure concerning a specific limit state for different levels of seismic intensity.…”

With regards to the process equipment nested in industrial frame structures, literature is again scarce (e.g., Merino Vela et al 2019), while on-ground supported equipment, such as transformer bushings (e.g., Brennan and Koliou 2020) or vessels founded at the ground level, are more widely studied and documented (Diamanti et al 2011;Wieschollek et al 2013;Korndörfer et al 2017).…”

A seismic fragility assessment methodology is presented for equipment-supporting reinforced concrete and steel buildings that are typically encountered in oil refineries. Using a suite of hazard-consistent ground motions and reduced-order models, incremental dynamic analysis is performed to obtain the seismic demand of the structural systems examined.Appropriate drift-and floor acceleration-sensitive failure modes are considered to define the limit state capacities of the supporting structure and the nested non-structural process equipment. Special care is exercised on the demand and capacity representation of structural and non-structural components, offering a transparent roadmap for undertaking analytical fragility assessment for equipment-supporting buildings typical to an oil refinery. The findings and the proposed methodology can be exploited by designers and facility managers for mitigating the risk of failure prior to the occurrence of an earthquake event, for designing the pertinent structures and their non-structural components by means of a risk-aware performance-based methodology, or as feed data in early warning systems.

“…A handful of studies is available on the seismic fragility of reinforced concrete (RC) chimneys via numerical models (e.g. Huang et al 2004;Gould and Huang 2006;Zhou et al 2015Zhou et al , 2019Guo et al 2018Guo et al , 2019Qiu et al 2020), while contributions on steel chimneys and process towers are very scarce (e.g. Lopez et al 1996;Moharrami and Amini 2014).…”

The seismic fragility is assessed for typical high-rise stacks encountered in oil refineries, namely process towers, chimneys, and flares. Models of varying complexity were developed for the structures of interest, attempting to balance computational complexity and accuracy regarding the structural dynamic and strength properties. The models were utilized along with a set of hazard-consistent ground motions for evaluating the seismic demands through incremental dynamic analysis.Demand/capacity-related uncertainties were explicitly accounted for in the proposed framework. Damage states were defined for each of the examined structure considering characteristic serviceability and ultimate limit states. Τhe proposed resource-efficient roadmap for the analytical seismic fragility assessment of typical high-rise stacks, as well as the findings of the presented research work are available to be exploited in seismic risk assessment studies of oil refineries.
