Moderate-to-large magnitude earthquakes still represent a major issue for the safety of ordinary and critical infrastructure. Despite significant 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 effective risk assessment methodologies. My research focuses on combining a fundamental insight into the mechanical behavior of structural systems with the application of the related scientific findings to the Earthquake Engineering practice. According to this, my talk will start with an overview on my research background, with a focus on 1. the development of a mechanics-based shear model for steel-concrete truss beams followed by the derivation of the relevant capacity equations and on 2. the development of a mechanics-based 3D model for friction pendulum bearings. The second part of the presentation will revolve around the current research I am conducting at the Lawrence Berkeley National Laboratory, which aims at developing an advanced simulation environment at the exascale for a coupled assessment of earthquake hazard and seismic structural risk. A general methodology for the evaluation of the structural risk and its application to a pilot study will be presented. The third and concluding part of the talk will focus on my research vision and plan. Emphasis will be given to the potential of the proposed methodology for estimating the structural risk mitigation of seismic isolation systems and to the migration from deterministic-based risk models to probabilistic-based risk models.
