Resumen
Site response analysis is crucial to define the seismic hazard and distribution of damage during earthquakes.
The equivalent-linear (EQL) is a numerical method widely investigated and used for site response
analysis. Because several sources of uncertainty are involved in this type of analysis, parameters defining
the numerical models need to be identified from in-situ measurements. In this paper, a Bayesian inference
method to estimate the expected values and covariance matrix of the model parameters is presented.
The methodology uses data from downhole arrays recorded during earthquakes. Two
numerical applications show the good performance and prediction capabilities of the proposed approach.
