Abstract

The axial force of high-strength bolts has always been the focus and inspection content of steel structure bridges during the operation period. However, the existing specifications do not give clear regulations on the inspection method. This paper discusses the applicability of the ultrasonic testing method in the detection of high-strength bolt axial force through a comprehensive comparison test between laboratory test and bridge structure field test. The results show that the ultrasonic testing method used in bolt axial force detection has the advantages of no damage to the bolt structure, retestability, high efficiency, etc., the test accuracy and stability are good, and it has a high promotion value.
