Seismic Performance and Analysis

Seismic performance and analysis is concerned with predicting how structures respond when the ground shakes — quantifying the forces, displacements, and damage that buildings, bridges, and infrastructure experience during earthquakes. Because ground motion is inherently uncertain in both timing and character, researchers rely heavily on probabilistic methods and empirical models to translate hazard estimates into realistic assessments of structural risk, often expressed through fragility functions that link shaking intensity to the likelihood of reaching different damage states. A central challenge is bridging the gap between the physics of dynamic structural response and the practical demands of performance-based design, where engineers must make decisions under deep uncertainty about future earthquakes. Active research directions include improving ground motion prediction for near-fault and site-specific conditions, developing higher-fidelity nonlinear simulation methods, and creating retrofit strategies that can cost-effectively reduce the vulnerability of existing structures built before modern seismic codes.
