Smartphone-based and data-driven superstructure state prediction method for highway bridges in service

HIGHLIGHTS

• who: Jixin Duan et al. from the School of Civil Engineering, Zhengzhou University, Zhengzhou, China have published the paper: Smartphone-Based and Data-Driven Superstructure State Prediction Method for Highway Bridges in Service, in the Journal: Sensors 2022, 5620 of /2022/
• what: The equipment used in the experiment shownphone in Table 2. accelerometer. To measure the change of the fundamental frequency of the bridge uniformly, the authors propose the frequency ratio Fb as a unified indicator to characterize the change of the fundamental frequency of the bridge.
• how: In this experiment the pulsation . . .
