Anderson Pires completed his secondment at Phimeca Engineering in Paris

Anderson Pires, a PhD student from our Chair, recently finished a three-month secondment at Phimeca Engineering in Paris as part of the GREYDIENT project. During this time, Anderson worked on applying stochastic emulators to assess the reliability of structures exposed to seismic activity.

The main goal of his research was to calculate fragility curves for structures under earthquake conditions. To do this, Anderson used stochastic emulators on simplified models of nuclear power plant structures. The seismic data he analyzed came from actual recorded earthquakes.

Anderson’s results show that stochastic emulators could significantly improve how we assess the reliability of structures. This method allows for quick evaluation of structural vulnerability across different seismic scenarios while considering the uncertainties in both the seismic data and the structural response. The emulators also address many of the challenges in current methods, offering more flexibility and better handling of heteroskedasticity. These advancements could lead to more accurate and cost-effective assessments of structural safety.
