摘要：In model updating of large-scale and complex civil infrastructure systems, a large number of updating parameters are involved and physical parameters related to local damages may be insensitive to structural response measurements, which are consequent on time-consuming, high costing and false-positive results. The response surface (RS) method based on radial basis functions (RBFs) can provide an effective approach to alleviate these problems, and its advantages and feasibility have be theoretical analysis and experimental validation. In this study, this approach is to further validate the effectiveness by applying on real-world civil engineering structures. A real-world large rigid-continuous concrete bridge is used to validate the applicability of this approach. A pre-analysis of numerical study about small changes of the updating parameters is first implemented for validation, and then model updating based on measurements is conducted. The updated parameters can achieve reasonable explanations and consistent with the practice. This method works well and can be easily implemented in practice for model updating of complex bridges. ? 2015, International Society for Structural Health Monitoring of Intelligent Infrastructure, ISHMII.
