　　This paper presents a finite element (FE) model updating procedure applied to complex structures using maximum likelihood estimation approach.Since FE-analysis of complex structures often consumes lots of computing resources,updating process,which needs to invoke FE-analysis analysis multiple times,may suffer from an unbearable amount of computation.Faced with the above problem,we develop a model updating framework based on maximum likelihood theory.
