How can we make buildings more resilient before – and after – earthquakes? We put one solution to the test
Philippines Red Cross/Getty Images This week’s magnitude 7.8 earthquake in the Philippines came with scenes familiar to New Zealanders: collapsed buildings, shattered facades and streets strewn with rubble. Earthquakes of such force test buildings to their extreme limits. As occurred this week, and in Christchurch in 2011 , some ultimately fail with tragic consequences. But, for structural engineers, preventing collapse is only part of the challenge. Increasingly, we are also
Researchers have tested a novel timber-based modular building system designed to enhance earthquake resilience. This innovative approach allows different levels of the structure to move independently during seismic events, rather than acting as a single rigid unit. This controlled movement aims to significantly reduce strain on the building and minimize damage. Following the simulated earthquake, the system is engineered to help the structure return to its original position, facilitating quicker reoccupation and reducing repair costs.
This development is significant as it offers a sustainable and resilient building solution that could reduce long-term repair costs and environmental impact after earthquakes.
