A data-driven approach for post-earthquake posting of buildings is presented. The approach is based on the analysis of residuals obtained by
subtracting the measured responses from reference signals that reflect the behavior of the healthy system. The residuals are used to compute
two indices from which the impact of the motion on the structure is assessed. One index measures the extent of nonlinearity and the other looks
at changes in structural characteristics after the strong motion part of the record is over. Results obtained for a number of buildings taken
from the CSMIP database suggest the approach may be suitable for automated posting.
