“…Many bridges throughout in the world have been installed with structural health-monitoring systems to monitor the strains, acceleration and frequency and identify the structural performance and damages [ 1 , 2 , 3 ]. Moreover, the data are also applied to update the Finite Element Model (FEM) of bridges, and then the numerical results agree well with the field-measured ones [ 4 , 5 , 6 ]. With an updated FE model, the response and performance of a bridge can be predicted well to evaluate its structural health conditions for safe operation [ 7 , 8 , 9 ].…”

“…Modelling the structural complexities of cable-stayed bridges, such as tower movements, support conditions and cable pretensions, is applicable through the FE method. In recent years, a variety of studies have been presented on FE modelling of cable-stayed bridges (Abdel-Ghaffar and Nazmy 1991; Wilson and Gravelle 1991;Zhu, Xiang, and Xu 2000;Zhang, Chang, and Chang 2001;Daniell and Macdonald 2007;Benedettini and Gentile 2011). However, the verification of bridge responses with field test results indicates that most of the priori FE models cannot accurately represent the real bridge conditions.…”

“…These methods first identify the uncertain parameters through a comprehensive sensitivity analysis and systematically change the parameters to minimise the discrepancies between FE model and test data often conducted using an iterative procedure. Several successful case studies can be found in literature using automated sensitivity based model calibration methods predominantly in flexible structures such as footbridges, long-span highway bridges, bridge towers and tall buildings [13][14][15][16][17][18][19][20].…”
