BERKELEY — In a testament to the value of high-quality construction, a full-scale three-story woodframe apartment building sustained only minor to moderate damage after University of California, Berkeley, engineers put it through a series of powerful shake tests.


UC Berkeley shake table featured on NBC's "Dateline"

The central feature of this recently upgraded research facility is a 20' x 20' "shake table" that can simulate many ways the earth can move during quakes. The table is capable of testing structures up to 40 feet tall and weighing up to 60 tons. The two-story test house built over a garage was the first such structure tested on the table.

This series of shake table tests resulted in an average total foundation settlement of 28 cm and 42.7 cm during two shaking sequences. The measured foundation settlements were compared to the estimated foundation settlement obtained from Liu and Dobry [1997] and Bray and Macedo's [2017] simplified procedures.
