Abstract A response surface method was utilized for the finite element model updating of a cable-stayed bridge in this paper to establish a baseline finite element model (FEM) that accurately reflects the characteristics of the actual bridge structure. Firstly, an initial FEM was established by the large-scale finite element software ANSYS, and the modal analysis was carried out on the dynamic response measured by the actual bridge structural health monitoring system. The initial error was obtained by comparing the dynamic characteristics of the measured data with those of the initial finite element model. Then, the second-order… More >
