Compressive Strength Analysis of a Steel Bolted Connection under Bolt Loss Conditions

The aim of the study is numerical analysis a bolted connection under conditions loss bearing capacity some fasteners in this connection. joined plates were made 3D finite elements, while treated as hybrid models consisting rigid heads and nuts flexible beams between them. A model unilateral contact with friction was used plates. first preloaded according to three different tensioning sequences normalised force. After all bolts tensioned, selected removed, simulating bolt damage loading conditions. tested for external compressive loads up 210 kN. effect loosening on load remaining at stage operation investigated.
