Abstract
Development of methodology for accurate and reliable condition assessment o f civil structures has become increasingly important. In particular, the fi nite element (FE) model updating method has been successfully used for cond ition assessment of bridges. However, the success of applications of the me thod depends on the analytical conceptualization of complex bridge structur es, a well-designed and controlled modal test and an integration of analyti cal and experimental arts. This paper describes the sensitivity-analysis-ba sed FE model updating method and its application to structure condition ass essment with particular reference to bridges, including specific considerat ions for FE modeling for updating and the model updating procedure for succ essful condition assessment. Finally, the accuracy analysis of damage asses sment by model updating was investigated through a case study. (C) 2001 Els evier Science BY. All rights reserved.
