The structural response and progressive failure of batten to rafter connections under wind loads
This study examined the dangers of losing fasteners on the roof of a home during a cyclone by using a wind tunnel to test the connections and surveying past cyclone damage to finally create a model that demonstrates progressive and cascading failures within a simulation. The outcomes of this PhD have allowed for the design and construction of more resilient structural systems and techniques for retrofitting existing structures.

This study examined the dangers of losing fasteners on the roof of a home during a cyclone by using a wind tunnel to test the connections and surveying past cyclone damage to finally create a model that demonstrates progressive and cascading failures within a simulation. The outcomes of this PhD have allowed for the design and construction of more resilient structural systems and techniques for retrofitting existing structures.
