The 2016 Kaikoura Earthquake caused the collapse of precast concrete floor units in a modern building in Wellington, New Zealand. Following the earthquake, a working group was established to develop a guideline for the seismic assessment of precast floors. This presentation will summarise the key seismic vulnerabilities of hollowcore and double tee precast floor systems, methods to assess the drift capacity of such systems, and ongoing research on retrofit approaches.
