Performance-Based Earthquake Early Warning for Tall Buildings

The USGS ShakeAlert Earthquake Early Warning (EEW) system issues a warning to residents on the West Coast of the US seconds before damaging waves arrive, if the expected ground level shaking exceeds a certain threshold. However, residents in tall …

Quantification of Modeling Uncertainty in the Rayleigh Damping Model

Abstract Understanding and accurately characterizing energy dissipation mechanisms in civil structures during earthquakes is an important element of seismic assessment and design. The most commonly used model is attributed to Rayleigh. This paper …

Quantifying Modeling Uncertainty in Simplified Beam Models for Building Response Prediction

The use of simple models for response prediction of building structures is preferred in earthquake engineering for risk evaluations at regional scales, as they make computational studies more feasible. The primary impediment in their gainful use …
