Serious limitations and problems on the practical use of Structural Health Monitoring (SHM) and finite element (FE) modeling for the purpose of structural health monitoring and condition assessment are discussed in this paper. The key issues in FE modeling of long2span bridges for health monitoring and condition assessment has been studied by our group for several years. The FE models of the TsingMa Bridge (TMB) in Hong Kong and Runyang Yangtse Bridge (RYB) in Jiangsu have been developed respectively for the purpose of structural health assessment and installation of a structural health system on RYB. The result shows that the model for the purpose of health assessment should be developed on the basis of transition theory for linking elements between local-scale at material points and full-scale at the structural level. Model updating and validation are necessary for an accurate modeling of the complicated bridge structures. Some critical components are determined from the analysis of the structural response by using the FE model of TMB in full-scale, then the local FE models are developed and used to determine the behavior of hot-spot stress and fatigue accumulation at critical locations.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
