Comparison of Seismic Performance Assessment Using Observed or Simulated Ground Motions in Seismic Hazard Analysis and Ground Motion Selection

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2449-2465, August 2026.
ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.

Seismic Meta‐Fragility Functions

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2504-2510, August 2026.
ABSTRACT Fragility functions make for one of the three key components of probabilistic seismic risk analysis, along with hazard and consequence and/or exposure models. They are, in principle, construction‐specific; however, risk analysis is more often performed on a larger (e.g., regional) scale. In this case, so‐called typological fragility curves are

Seismic Fragility and Vulnerability of Partially Grouted Flexural‐Controlled Reinforced Masonry Buildings in Colombia

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
This paper presents the development of analytical fragility and vulnerability functions for flexure‐controlled partially grouted reinforced masonry (RM) buildings that are representative of Colombian urban areas, with the goal of enhancing national seismic risk assessments.

Quantifying Multidimensional Effects in Linear Site Response Using 1D and 2D Simulations of Sedimentary Basins in Wellington, New Zealand

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
This study quantifies the influence of multidimensional effects on site response in the Wellington region of New Zealand by comparing results from different simulation approaches. Response‐spectral amplification functions from 1D and 2D site response analyses are compared to quantify the magnitude and spatial distribution of multidimensional effects ...

Nonstationary Spatial Correlation of Earthquake Ground Motions in California

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
Assessing seismic risk to spatially distributed infrastructure systems requires realistic representations of spatially correlated ground motions. Existing models for the spatial correlations of ground motions rely on strong second‐order stationarity assumptions, under which the correlation structure is assumed to be invariant across space, potentially ...
