摘要：
Deflection is an important parameter to evaluate the safety performance of bridge. Measuring deflection accurately is a research hotspot in the field of bridge health monitoring. This paper presented a method to restructure the deflection response based on the rotation data, which can restructure the deflection response accurately at the adjacent beam section with the rotation data of the appropriate measuring point. According to the bridge geometric parameters and load location information, the relationship between deflection response and rotation response was established. Combined with the measured rotation response data, the intermediate variables were identified, and then the bridge deflection response information was calculated to restructure the bridge deflection response curve with the data of the rotation measurement point. Numerical simulation and model test were carried out. The results show that the restructuring method of bridge deflection response is highly consistent with the actual deflection response; On the other hand, the method can reconstruct the deflection response based on a single rotation response by combining load information and bridge geometric parameters, which has good practicability. © 2022, Editorial Office of Journal of Vibration and Shock.
