サマリー
あらすじ・解説
In this episode of Disaster Discussions we're joined by Dr. Geoff Boughton, Adjunct Associate Professor at the James Cook University Cyclone Testing Station and Dr. Korah Parackal, IBHS Research Engineer and Adjunct Senior Research Fellow at the James Cook University Cyclone Testing Station. This discussion looks back at the evolution and landfall of category four Cyclone Tracy that struck Darwin, Australia on Christmas Eve 1974, leaving 90% of the town's residential homes uninhabitable and tens of thousands of residents homeless. We discuss how Tracy's devastating impact sparked changes to the way Australia's housing was built, and how these changes eventually led to a nationwide building code. Today homes in Australia are structurally engineered to withstand high winds throughout the entire country and include provisions for low cycle fatigue, a continuous load path or tie-down chain, and are designed for high internal pressures.
