Abstract: To study the joint performance and failure characteristics of pretension high-strength bolts of fabricated steel structures, the resistance strain gauge method was used instead of the traditional torque method to analyse the loading failure of slip specimens. The refined finite element model and the extended finite element model based on linear elastic fracture mechanics were established and their results are compared with the experiments. The results showed that the anti-slip coefficient of the untreated clean rolled Q235 steel conforms to the given value of the code. The finite element simulation results were in good agreement with the test results, and the different failure modes on cover plates or core plate respectively occur in the specimens with different thicknesses of core plates.
