Abstract

This paper looks at the sensitivity of the seismic fragility evaluation of a typical multistory shear frame with respect to the pattern of the missingness of relevant structural appraisal data. With continuous development of conventional structural assessment routines and recent advances in structural health monitoring (SHM) techniques, obtaining the latest information on the condition of a structure has been finding its applications to seismic fragility analysis. An accompanying issue is that the structural appraisal data practically acquired may often be incomplete. The data missingness here could be attributed to a series of reasons including data acquisition system outage, data transfer error, etc.. The influence of the appraisal data missingness on the subsequent seismic fragility evaluation is quantified in this study. Specifically, the multivariate-normality and missing-completely-at-random (MCAR) assumptions are applied.
