In light of the recent magnitude 7.8 earthquake in the Philippines, the need for resilient building designs has become increasingly urgent. Structural engineers are exploring how buildings can not only survive earthquakes but also recover quickly with minimal damage. Recent tests conducted at the University of Auckland on a modular cross-laminated timber (CLT) building showcased its potential as a sustainable construction material. CLT, made by bonding layers of timber, offers a low-carbon alternative to traditional concrete and steel, storing carbon and reducing overall emissions. During the tests, the building was subjected to earthquake-like motions, demonstrating a self-centring feature that allowed it to return to its original position post-shaking. This capability could lead to lower repair costs and quicker restoration of use after seismic events. Although the tests did not evaluate non-structural elements, the results indicate that modular timber buildings can effectively withstand and recover from earthquakes. The next phase involves integrating this technology into complete building systems and assessing their practicality and long-term performance, potentially paving the way for safer, more resilient, and environmentally friendly buildings.
