Design of CFRP Anchorage to Improve Blast Performance of Mitigated Concrete Slabs (Recorded Presentation)

Video Transcription

Video Summary

Dr. Sarah Horton, an associate professor at the University of Missouri-Columbia, delivered a talk on enhancing blast performance of concrete slabs using CFRP Anchorage. Her research investigates structural strengthening, especially in close-range blast scenarios, by employing carbon fiber reinforced polymer (CFRP) to achieve maximum structural integrity and ductility. Despite traditional steel's efficacy, CFRP's lighter weight makes it the focus of Horton's efforts, requiring effective anchoring to fully utilize its tensile capacity. Through innovative use of spike anchors in concrete, she illustrated how CFRP can prevent debonding and maximize strain capacity, crucial for intense blast mitigation. Outcomes showed CFRP, combined with steel plates, improves structural resilience during blasts. More research is necessary to refine design standards and verify anchor efficiency in varying blast conditions, but Horton's work underscores CFRP's potential in structural engineering for enhanced blast resistance.
