Risk‐Targeted Seismic Design Maps for Mexico

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 336-349, February 2026.
ABSTRACT Risk‐targeted seismic design maps for Mexico are presented. Risk‐targeted approach establishes an acceptable risk level, measured with the annual collapse probability, to determine seismic design coefficients. Seismic design maps are calculated for an annual probability of collapse of 1 × 10−4 and 2 × 10−4.
