Timber products formed diaphragms, beams and columns, while steel gravity connections were detailed to accommodate up to 5% rotation with minimal damage.<\/p>\n\n\n\n
The researchers subjected the hybrid building to simulated earthquakes across multiple configurations, including motions scaled to the risk\u2011targeted maximum considered earthquake. The team reported the building \u201csuffered virtually no structural damage\u201d and that \u201cafter each one we could walk right back into the building,\u201d underscoring repeatable, repairable performance.<\/p>\n\n\n\n
\u201cIf there\u2019s a big earthquake, we want buildings to protect people, but the buildings themselves are often structurally compromised and have to be torn down,\u201d said Andre Barbosa, the Cecil and Sally Drinkward Professor in Structural Engineering. Barbosa, which last year said the team could \u201creplace six\u2011story walls and still have a resilient structure that could sustain another 20, 40, or 60 earthquakes.\u201d <\/p>\n\n\n\n
The tests were conducted at the NHERI@UCSD outdoor shake-table facility, with support from the National Science Foundation, the TallWood Design Institute, and multiple industry partners. Test data are archived in the DesignSafe repository (project ID PRJ\u20115736) to enable model calibration and further study. These results provide regulators and designers with concrete evidence to inform code updates and resilience planning, thereby strengthening the argument for taller mass-timber buildings in seismic regions.<\/p>\n\n\n\n
