- Abstract:
- The domestic class 8.8 self-lock one-side bolt STUCK-BOM was developed. The axial tensile and shear static tests of single bolt for 6 different types of class 8.8 self-lock one-side bolts with varied steel plate thicknesses were carried out. The load-displacement curves of domestic class 8.8 self-lock one-side bolt under axial tension and shear force were obtained through experiments. The mechanical properties, such as ultimate tension bearing capacity, ultimate shear bearing capacity and initial stiffness of single one-side bolt were obtained. The results show that except for the thinner connection steel plate, the tension bearing capacity of one-side bolt is equal to the same grade high-strength bolt and the shear bearing capacity is better. The one-side bolt can meet the requirements of engineering application. The research can provide basic data and basis for the engineering application of domestic class 8.8 self-lock one-side bolt for steel structure.
