Investigating the Structural Failures Behind Arecibo's Collapse

The collapse of the Arecibo Observatory's telescope in 2020 is attributed to zinc creep in cable sockets, potentially accelerated by electroplasticity due to electromagnetic radiation, according to a National Academies report. The report suggests that the unique electromagnetic environment of the telescope may have hastened the failure, despite a safety factor above two. The NSF plans to replace the telescope with a science education center and is considering the report's recommendations for future projects.

Uncovering the Cause: Analyzing the Arecibo Collapse

Forensic analysis of the Arecibo radio telescope collapse has identified bad sockets as the main cause of the failure. The investigation revealed that the manual and inconsistent splay of the wires during cable socketing led to shear stress, causing the molten zinc "spelter socket" to slowly flow around the cable strands and allowing them to slip out of the surrounding steel socket. While there were multiple causes for the collapse, being able to attribute the bulk of the failure to a single defect provides valuable lessons for preventing future failures of cable-supported structures.
