As part of the ShakeOut event held in mid November 2008 to increase earthquake preparedness in southern California, nees@UCLA along with the television station KCET held a demonstration at UCLA's state-of-the-art research laboratory to illustrate the improvements made to design requirements for reinforced concrete structures in the past few decades, as well as the importance of continued research in this field. The demonstration tested two columns with identical external dimensions, but different internal steel reinforcement. The reinforcement in one column was designed based on old code requirements, the other with more modern requirements set forth by the American Concrete Institute (ACI). A cyclic lateral load was applied simultaneously to both specimens. This simulated earthquake demonstrated the increased capacity of the column designed with modern requirements to withstand earthquake loading.
A similar test will also be conducted on November 13, the actual day of the Great ShakeOut.
