“…For instance, in the 2010 Mw 8.8 Maule, Chile Earthquake, approximately 125 million liters of wine were lost, equivalent to about 250 million US dollars. This loss represented 12.5% of 2009's year production even though the earthquake occurred a few weeks before the 2010 annual grape harvest 25 (i.e., not all tanks were at maximum capacity). The same poor performance was observed again in later events, such as the 2011 Christchurch, 2013 Marlborough, and 2016 Kaikōura Earthquakes in New Zealand, 26,27 the 2012 Emilia Earthquake in Italy, 28 the 2014 South Napa Earthquake in the USA, 29 and again the 2015 Coquimbo Earthquake in Chile.…”

This paper presents the numerical and experimental evaluation of a vertical‐rocking isolation (VRI). This evaluation is done by 1‐D shaking table tests performed on a full‐scale legged storage tank of 3000‐liters capacity and its representation through a simple yet representative rigid lumped‐mass model approach. The isolation system setup consisted of four ISO3D‐2G devices, each one placed on each leg of the tank, which uses high‐damping natural rubber to generate the restoring and dissipative forces. The ISO3D‐2G device is vertically flexible and laterally rigid, enabling the isolation mechanism of the rocking motion of the tank. The experiments were carried out using three white noise for the system identification and 17 ground motions inputs for the system validation. The measured variables included the lateral acceleration and displacement of the tank, and the vertical and rotational behavior of the isolation interface. The identification results showed a vertical‐rotational coupled fundamental mode that is highly dependent on the amplitude of deformation, with a period varying from 0.5 to more than 1 s, depending on the intensity of the motion. The maximum displacement of the tank at the top remained below 13 cm with total accelerations of nearly 0.3 g, both for motions with Peak Ground Acceleration (PGA) values ranging from 0.3 to 0.8 g. The mean maximum values were predicted with the simplified model with errors of less than 10% and 21% for displacements and accelerations, respectively. Finally, the results show that the behavior of vertical‐rocking isolated structures can be predicted by simplified models with reasonable errors and that the development of simple design guidelines and equations for VRI systems is possible.

“…5). Throughout the years, extensive damage has been found for steel tanks that were not properly designed or detailed against seismic action (González et al 2013;Manos 1991;Niwa and Clough 1982;Zareian et al 2012), with the most common types of damage and failures including the buckling of the tank shell, roof damage due to convective wave motion, settlement of foundations, failure of piping systems connected to the tanks, plasti cation of the base plate in unanchored tanks due to uplifting, sliding of the tank, failure of anchor bolts and spillage of toxic material due to excessive sloshing (Brunesi et al 2015;Niwa and Clough 1982). To account for this, three different tank con gurations with different aspect ratios were considered, each having broad (Tk-1), intermediate (Tk-2), and slender (Tk-3) structural con gurations with different lling levels of 90% and 80% of their total capacity, given its impact on the dynamic response of the structure.…”

Industrial plants are quite susceptible to NaTech disasters during earthquakes caused by damage to structural and non-structural components and the potential release of toxic materials. To mitigate and manage this risk, the ROSSINI project was initiated and its results are described here for what concerns industrial plant worker safety and their risk-based navigation in emergency situations. The project includes a data acquisition system consisting of a data acquisition board and an array of different sensor technologies, which process the seismic event and other meteorological information before passing them as inputs towards the risk identification and evaluation (RIE) modules. Here, the risks associated with structural and non-structural damage and health risks associated with the release of harmful substances are estimated and combined to form a navigable risk map. This map is used within a purpose-built risk-based navigation application for the safe egress of workers from an industrial plant. To demonstrate the implementation of this system, two case-study industrial plant layouts consisting of buildings, non-structural components, liquid storage tanks, piping systems, and chemical storage vessels, were devised. This paper describes the project’s implementation in these contexts and illustrates the results via several example scenarios.

Investigating the structural behaviour and buckling susceptibility of cylindrical oil storage tanks is crucial for ensuring their safe and reliable operation. In this study, the structural behaviour and buckling susceptibility of closed roof-top cylindrical oil storage tanks under combined internal and external pressure scenarios were investigated using the finite element analysis (FEA) technique. By utilizing the FEA technique, the combined effect of wind-induced pressure of 250 Pa, applied on the outer surface of the tank and internal pressure of 0.5 MPa, applied on the outer surface of the storage was analysed. The result reveals significant stress concentrations and deformation patterns, particularly on the windward side of the tank, thus, emphasizing the susceptibility of the storage tank to buckling under the specified operating conditions for both the filled and half-filled tank; with internal pressure emerging as the primary contributor to mechanical strain and deformation experienced in the tank, while the wind load plays a secondary but significant role in the deformation of the tank. The fe-safe predicted useful life shows that under the specified operating conditions, the filled storage tank will survive 1 429 hours (2 months) while the half-filled tank will survive 3 551 hours (5 months) before failure due to buckling. Thus, the useful life estimation results show the importance of varying oil levels and operating conditions in the structural assessments of storage tanks.
