Ductile connection to improve the fire performance of bare-steel and composite frames

Purpose In order to improve the robustness of bare-steel and composite structures in fire, a novel axially rotationally ductile connection has been proposed this paper. Design/methodology/approach The component-based models have incorporated into software Vulcan facilitate global frame analysis for performance-based structural fire engineering design. These are validated against detailed Abaqus FE experiments. A series 2-D 3-D with connections, idealised rigid pinned created using compare performance other types structures. Findings comparison results show that can provide excellent ductility accommodate axial deformation connected beam under conditions, thus reducing forces generated potentially preventing premature brittle failure connection. Originality/value Compared conventional types, exhibits considerable deformability, enhance fire.
