Advanced Simulation Methodologies for Seismic Hazard and Risk Assessment: SEMM Seminar
Seminar | April 17 | 12-1 p.m. | 502 Davis Hall
Dr. Floriana Petrone, Postdoctoral Research Fellow, Lawrence Berkeley National Laboratory
Moderate-to-large magnitude earthquakes represent a significant risk around the world and a major issue for the safety of ordinary and critical infrastructures. Despite major advances in the seismic engineering field, much research is still needed to gain better understanding of the science and engineering behind earthquake phenomenon and develop risk assessment methodologies. Current research at the Lawrence Berkeley National Laboratory aims at developing an advanced simulation environment at the exascale for a coupled assessment of earthquake hazard and seismic structural risk. The first part of the talk will present a stochastic geophysical model being developed to understand the implications of realistic three-dimensional earthquake input motions on the seismic hazard assessment. The second part will focus on a general methodology for the evaluation of the structural risk and its application to a pilot study. The final part of the presentation will show the potential of the proposed methodology for estimating the structural risk mitigation of seismic isolation systems with an insight into the case of Friction Pendulum bearings.
