Professor Astroza has been awarded a Fondecyt Regular Research grant. In this 4-years project novel approaches to simulate the response of structural systems subjected to multiple hazards during their service life, including recurring earthquake events, local scour, and aging effects will be developed. The project will focus on reinforced concrete structures with chloride-induced corrosion as the principal environmental stressor affecting the long-term performance due to aging.

This project will propose an advanced uncertainty-informed multi-hazard risk assessment approach by integrating model calibration (uncertainty quantification) of material and component-level models using experimental data, development of state-of-the-art FE formulations for modeling and seismic response analysis of large-scale soil-foundation-structure-interaction systems including time-varying material deterioration and local scour effects, and propagation of uncertainties to determine fragility curves.
