Bolted steel splice connections play a critical role in the continuity and integrity of structural steel members. During a fire, these connections are subjected to extreme thermal and mechanical demands that can significantly alter their performance. Understanding their behavior under elevated temperatures is essential for ensuring the fire resilience of steel-framed structures
In this practical example, the beams, bolts, and steel plates are modeled as 3D parts. In the first stage, a heat-transfer and fire analysis is carried out through a Heat Transfer step. The results from this analysis are then imported into the static structural analysis to obtain the stresses and deformations of all parts under fire conditions. All modes of heat transfer—convection, conduction, and radiation—are included
After the simulation, all results such as stress, strain, temperature, heat transfer, and … are available. You can see some figures of the results below
