Storage tanks are crucial components in industrial facilities and building plants, particularly when it comes to seismic events. The collapse of these tanks can lead to the release of hazardous substances, posing risks to both human safety and the environment. This research paper focuses on assessing the seismic performance of a liquid-storage tank installed in industrial steel moment-resisting and braced frame buildings. The evaluation of the tank’s seismic performance is done through fragility curves, which are developed for various limit states that impact the tank. Different building configurations were considered, and the tank’s location varied across the structure’s different floors. The findings emphasise the significance of developing corresponding fragility models based on different intensity measures. Additionally, the study examines absolute acceleration floor response spectra and relative displacement floor response spectra in detail to characterise the seismic demand. Ultimately, the research suggests that the intensity measure currently used for secondary components, such as peak floor acceleration, may not be optimal. Therefore, future advancements should focus on creating updated fragility curves for non-structural elements by utilising more effective intensity measures.

Abstract
Storage tanks are crucial components in industrial facilities and building plants, particularly when it comes to seismic events. The collapse of these tanks can lead to the release of hazardous substances, posing risks to both human safety and the environment. This research paper focuses on assessing the seismic performance of a liquid-storage tank installed in industrial steel moment-resisting and braced frame buildings. The evaluation of the tank’s seismic performance is done through fragility curves, which are developed for various limit states that impact the tank. Different building configurations were considered, and the tank’s location varied across the structure’s different floors. The findings emphasise the significance of developing corresponding fragility models based on different intensity measures. Additionally, the study examines absolute acceleration floor response spectra and relative displacement floor response spectra in detail to characterise the seismic demand. Ultimately, the research suggests that the intensity measure currently used for secondary components, such as peak floor acceleration, may not be optimal. Therefore, future advancements should focus on creating updated fragility curves for non-structural elements by utilising more effective intensity measures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
