Researchers at NIST, alongside experts at UC San Diego, put do | PBD
Researchers at NIST, alongside experts at UC San Diego, put dozens of steel columns (the kind used in multistory buildings) through the seismic wringer to learn how they might hold up during an earthquake. With a powerful hydraulic system called a shake table, they replicated the shaking ground motions during a seismic event, crumpling many of the columns prematurely.
They gained more than contorted metal from the tests, however. The team was able to use the data to devise new design limits for steel columns that have been worked into a draft American Institute of Steel Construction standard. If they appear in the final version, they could potentially bolster the resilience of steel columns on shaky ground. Find out how: https://lnkd.in/gFP2F2b7
