PORTLAND, Ore. (KOIN) — Portland State University and local design professionals on Tuesday ran earthquake tests on beam-column components that may be used as part of the framework for the tallest timber high-rise building in the U.S., set to be constructed in the Rose City in 2017.

The building will be 12 stories, and this test will ensure that the wood structure can withstand earthquakes.

Below find PSU’s description of the test.

The test involves a slow racking movement, simulating earthquake demands on a full-scale beam-column-floor assembly. The intended performance of this component under these large movements is minimal damage and no collapse during earthquakes. Given the importance of seismic resilience for our region, this work represents a significant advancement in sustainable construction of high-rise buildings.

The test was performed at PSU’s Infrastructure Testing and Applied Research Laboratory (iSTAR) on Southwest 10th Avenue.
