UCSD 7 Story Building Shake Table Test

Between October of 2005 and January 2006, a full-scale vertical slice of a seven-story reinforced concrete wall building (shown at your right) was subjected to increasing intensity of uniaxial earthquake ground motions on the new NEES Large High-Performance Outdoor Shake Table located at UCSD's Engelkirk Structural Engineering Center. Responses were measured using an extensive instrumentation array, and all results have been archived for future release. The largest input motion was the Sylmar Medical Facility free-field record obtained in the 1994 Northridge Earthquake, which is one of the strongest recorded motions from that event and includes some near-fault ground-motion characteristics. The building slice was designed using a displacement-based and capacity approach for a site in Los Angeles that resulted in design lateral forces that are significantly smaller than those currently specified in building codes used in the United States.
