Abstract:
Baseline finite element model is necessary for structural health monitoring system of Runyang Cable-Stayed Bridge to analyze the working conditions under various loads and the actual load capacity. Finite element modeling and optimization of Runyang Cable-Stayed Bridge based on measured cable force is presented. A spine finite element model with self-defined beam section is constructed. Then, the measurement results of static and dynamic load testing are taken as reference to optimize the model. The analytical cable force is iteratively updated until the analytical cable stresses are in good agreement with those measured. The optimization algorithm is implemented in Ansys as a novel structure analysis module. After optimization, the analytical results are in good agreement with those measured, including the stress and the modal frequencies. The differences between analytical and measured modal frequencies are less than 4%. This verifies that the optimization philosophy is effective and the optimized finite element model is able to be employed as baseline model in the structural health monitoring. Also, the solution to software development in Ansys for similar research is provided.
