“…The model is based on the [35] framework; however, since it takes into account also the interaction with shear forces, it results to be more accurate and reliable than the standards [35]. This is confirmed in the experimental work documented in [40].…”

The seismic risk assessment of industrial facilities mainly relies on historical data and analysis and design of uncoupled secondary components. Accordingly, the dynamic interaction between primary structures and process equipment is overlooked. The SPIF project -Seismic Performance of Multi-Component Systems in Special Risk Industrial Facilities-was carried out to respond to this gap, within the European H2020 SERA framework. Its objective regarded the investigation of the seismic behaviour of an archetype industrial multi-storey steel moment resisting frame (MRF) structure equipped with non-structural components (NSCs) by means of shaking table tests. The goal of the proposed study was to extend the interaction analysis between a primary multi-storey braced frame (BF) steel structure and NSCs in a performance-based earthquake engineering (PBEE) perspective. Along this vein, to excite the vibration periods of the NSCs and thus, enhance possible coupling with the primary structure, a synthetic site-based ground motion model (GMM) was employed. More precisely, the proposed research intended: i) to severely excite the process equipment and supplement the scarcity of real records with a specific frequency content by means of a stochastic GMM; ii) to quantify seismic-induced force and displacement demands of secondary components and their effects on the primary BF structure. The evaluation of the experimental data clearly shows buckling in the bracing system of the BF configuration and a strong interaction between vertical tanks and floor crossbeams of the BF. At the very least, the favourable performance of the archetype BF under strong seismic records is demonstrated.

“…In recent years, the use of bre optic (FO) sensor technologies in engineering and industrial applications has been increasing (Barrias et al 2016;Li et al 2004;Marino and Ciucci 2019;Paolacci et al 2021). This is primarily attributed to the several advantages they hold with respect to traditional sensors, such as being lightweight and durable, possessing immunity to electromagnetic elds, high sensitivity, good embeddability, and the capability of covering wide areas.…”

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.
