Numerical analysis on the bearing capacity of high strength bolt connection for longitudinal seam of corrugated steel plates

Abstract:

To study the bearing capacity of high strength bolt connection for longitudinal seam of corrugated steel plates (CSPs), finite element models of test specimens were established by ABAQUS software. Influences of end distance, bolt preloading, and waveform of high strength bolt on the bearing capacity of CSP connection were discussed. Results show that the end distance of CSP connectors should be larger than 3d₀ to avoid the shear fracture of the plate end. When bearing failure at bolt hole occurred, the bearing capacity gradually increased with the increase of bolt preloading. The calculation formula of the bearing capacity of CSP connectors was suggested to be multiplied by the increase factor of 1.1 on the basis of the calculation formula of China for calculating flat plate connectors. When bolt shearing failure occurred, bolt preloading had little effect on bearing capacity, and the calculation formula of the bearing capacity of CSP connectors could be calculated as that of flat plate connectors.
