Risk Assessment for the Seismic Protection of Industrial Facilities (RASOR)
Sponsor:
Ministry of Education – General Secretariat of Research & Technology
Program:
Thalis
Partners:
National Technical University, Athens
University of Thessaly, Volos
University of Patras
Institute of Technical Seismology and Anti-seismic Structures
Objective:
The research concerns the most important structural components in a typical industrial facility, i.e. liquid storage tanks, industrial pressure vessels, industrial piping systems and their supports. The primary target is to develop a systematic performance-based design and assessment methodology for the risk mitigation of industrial equipment structures. This target will be achieved through a multi-disciplinary approach and the development of simple and efficient numerical methodologies that allow computing the probability of structural failure (i.e. when structure is not able to meet the purpose for which it was designed), when subjected to typical ground motions representative of sites where major industrial facilities in Greece are located..
