This study investigates the stability of bolts in corrugated steel webs using a novel laser Doppler detection technique, with comparative analysis conducted on localized bolt models in ABAQUS finite element software. Fundamental frequency detection via laser Doppler reveals that the clamping force of Bolt #10 in the corrugated steel web is significantly inferior to safety levels observed in other bolts. Furthermore, finite element simulations and residual clamping force assessments were employed to model corrosion scenarios involving varying nut heights and thicknesses. An evaluation model for the clamping force loss ratio of high-strength bolts was established, demonstrating that corrosion depth profoundly impacts clamping force. Notably, trapezoidal and hourglass-shaped corrosion morphologies exhibit lower clamping force loss compared to conventional cutting. A bolt stability detection device with adjustable height and angle was designed. Combined with the positioning theory of corrugated steel web, the fundamental frequency detection found that the clamping force of bolt No. 10 was insufficient and needed on-site adjustment, providing data support for the evaluation of bolt connection reliability.
