Novel Metafoundations for Seismic Protection of Relevant Industrial Process Plant Components
Seismic events like the Fukushima 2011 and the recent disaster caused by the Maras doublet on 6 February 2023 highlighted the weaknesses of conventional construction methods and seismic protection systems under extreme conditions. Despite the existence of advanced safety measures and regulations, there is still a need for research and development of robust and innovative methods to enhance resilience against both natural hazards and human factors during construction and operation, while also satisfying the sustainability and efficiency requirements. Metamaterials and metastructures, which are nowadays carefully designed by engineers to exhibit specific properties to control wave propagation, have emerged as a promising area of research for seismic protection. Among various examples, metafoundations (MFs) based on locally resonant metamaterials have shown great potential as a simple and effective solution while also being beneficial for standardizing the design of critical infrastructure, industrial and nuclear power plants, and their components. The purpose of this study is to present the advantages and limitations of MFs and provide knowledge for future developments. Compared to traditional approaches, MFs offer multidirectional and adaptable seismic protection owing to their modular construction. Firstly, the study discusses the parameters that affect the performance of MFs and their correlation with each other, highlighting the design flexibility of MFs. Specifically, the adaptability of MFs was explored concerning reducing risk and allowing a single superstructure design to be used in different locations with varying demands and requirements, enabling the design standardization for the superstructure. The standardization aims to use the same -optimized, simplified and precisely studied- design of the superstructure to be constructed many times, which in return, reduces construction times, minimizes human error or influence during the construction stage, and enhances efficiency and sustainability. Additionally, special attention was paid to a novel mechanism of inerters to improve the performance and/or reduce the dimension of MFs. Finally, it was shown that the MFs with multiple layers can be more robust against the mistuning of resonators.
