What is Progressive Collapse in Structural Engineering? It’s a chain-reaction failure where the loss of one structural element leads to a disproportionate collapse of the structure. This happens when the system lacks redundancy, robustness, or alternate load paths to absorb localized damage. 👷‍♂️ To prevent it, structural engineers must: ✔️ Design for continuity and ductility ✔️ Provide horizontal and vertical tying systems ✔️ Strengthen or isolate key structural elements ✔️ Follow appropriate
