Progressive collapse performance of steel beam-column substructures with extended end-plate connections under fire

Key Points

• Progressive collapse resistance varies significantly with the design of end-plate connections, indicating enhanced safety features are critical.
• Key metrics reveal that steel beam-column systems show a 30% improvement in performance under fire conditions compared to traditional designs.
• Assessment focused on fire scenarios and the impact on structural integrity of beam-column connections in substructures involved.
• Results highlight the need for better design approaches to prevent failure in fire scenarios, ensuring safety in construction.
