INDUSE-2-SAFETY aims at developing a quantitative risk assessment methodology for seismic loss prevention of “special risk” petrochemical plants and components, e.g., support structures, piping systems, tanks and pressure vessels, flange and tee joints, etc.
The proposed probabilistic based methodology will ensure safe functioning / shutdown under ground motions of increasing spectral acceleration through extensive analytical, FE and experimental investigations. Related harmonized importance factors γI and limit state probabilities will a uniform hazard versus a uniform risk basis for EN 1990/EN 1998.
Goals
The INDUSE-2-SAFETY proposal is the direct continuation of the RFSR INDUSE project (2009-2012) focusing on onshore industrial plants at the system level inside the scope of EN 1998.

Quantification of the actual risk for seismic loss prevention of potentially dangerous “special risk” petrochemical plants
Development of a Seismic Probabilistic Risk-based Evaluation (SPRE) procedure capable of providing damage exceedance occurrence frequency for a representative prototype case study of a “special risk” petrochemical installation
Evaluation of fragility curves of main structures and components needed for the SPRE analysis, e.g. for support structures, piping systems, tanks, slim vessels, vertical cylinders, spherical storage tanks, flange and tee joints, etc.
Experimental investigation of steel storage tanks without/with floating roofs, piping network substructures, flange joints and tee joints by means of cyclic, real-time/pseudo-dynamic and shaking table tests.
Issuing of risk assessment provisions for seismic loss prevention of onshore “special risk” petrochemical facilities within the scope of EN 1998
Enhanced design recommendations for the improvement of several European standards and codes, including EN 1990, EN 1998, EN 13480-3 and EN 1591
