Dr Li is mainly fascinated in developing and applying (1) probabilistic and statistical methods to engineering risk/reliability problems, and (2) optimization methods to inverse engineering problems in the field of structural engineering. Engineering risk assessment consists of uncertainty quantification and propagation through physics-based (e.g., nonlinear finite element) and/or data-based modeling. This serves to assist decision-making in the process of probability-based design, retrofit, and maintenance in the face of uncertainty. He is also extensively involved with inverse engineering problems (e.g., structural design optimization, nonlinear FE model updating using field-recorded and experimental data). Specifically, his research interests includes:
Mechanics-based nonlinear FE modeling: Concrete/masonry structures, soil-structure-interaction, etc.
Probabilistic modeling: Stochastic modeling of natural hazard loads, traffic loads, deterioration processes, etc.
Structural reliability and risk: Uncertainty propagation, risk quantification, probability-based code calibration and design optimization.
Applications of reliability methods to various engineering structures: Concrete bridges, masonry buildings, steel girders/pipelines, etc.
Statistical modeling of expensive computer models: Bayesian model calibration, validation with error assessment, and uncertainty quantification
System identification: Statistical structural health monitoring, etc.
FE modeling and probabilistic assessment of aged structures: Structural deterioration (corrosion), fatigue, altered load condition, etc.
Earthquake engineering: performance-based engineering, seismic response modification strategies (e.g., isolation, self-centering technologies)
