RISK ASSESSMENT FOR THE SEISMIC PROTECTION OF INDUSTRIAL FACILITIES

Abstract: 

The project focuses on the seismic safety of industrial equipment structures (liquid storage tanks, pressure vessels and piping systems) and the development of computational methods for their seismic risk assessment through a performance-based earthquake engineering approach. Such structures are widely used plants for production and storage of hydrocarbons and chemical products (e.g. ammonia, VCM, NLG, propylene), refineries (petrochemical facilities) and thermal stations for energy production. It is therefore evident that their seismic behaviour and design differs substantially from that of ordinary Civil Engineering structures (buildings, bridges).

The particularities of those systems stem from their shape and geometry, the effect of the contained fluid (liquid or gas), the significant influence of initial imperfections, and the degradation of the material properties due to cyclic operation loads and aging. Currently, for this special type of structures, there are no performance-based earthquake engineering provisions, while their performance assessment follows the "˜allowable-stress design" concept.

Therefore, the project aims at formulating the seismic design framework for industrial equipment structures, through an inter-disciplinary effort with the synergy of Civil and Mechanical Engineers, together with Engineering Seismology experts. Therefore, the project is based on an integrated (holistic) approach, involving researchers from four research institutions and aiming at developing novel, efficient and reliable computational methods for assessing the seismic risk of industrial equipment structures considering seismic input representative of Greek sites.

The results of the project are expected to contribute to the safety and the structural integrity of industrial facilities in Greece, safeguarding their operation after a strong seismic event, and minimizing the risk to the population and the environment.
