Abstract:
A finite element model with three-dimensional solid elements was established to stimulate the bolted connection in nine groups of Q460 grade high strength steels. Non-linear material, geometrical and contact analysis were carried out to predict the load-displacement curves. The model-building procedure and solution programs were introduced in detail. Due to various end distance, edge distance and pitches, different failure modes were observed including end tear-out, bearing resistance and net-section facture. The effectiveness of the performed finite element analysis was verified by the comparison between calculation results and the experiment results. The results show that the finite element model in the paper can simulate bearing resistance of bolted connection in high strength steels. It's found that the appropriate stress-strain relations and contact stiffness are important parameters for accurate prediction.
