Abstract

The NEES UCSD Large High-Performance Outdoor Shake Table (LHPOST) is the largest outdoor was funded by the National Science Foundation through a major research equipment award and was commissioned in 2003.  The LHPOST has a payload capacity of 4,000 kips and was specifically designed to reproduce the high velocity pulses observed in near-fault earthquakes. Since its commission a number of landmark experiments in structural and geotechnical engineering have been performed on the LHPOST.  This seminar will review four prominent tests performed on the LHPOST, including the recent test on a full-scale 5-story building, which incorporated a range of nonstructural elements and was tested on a base-isolated and a fixed-based condition

José I. Restrepo is a Professor in Structural Engineering at the University of California, San Diego. He received a a Ph.D. from the University of Canterbury, New Zealand. His research interests are in the development of new structural systems for bridges, port structures and buildings.  Prof. Restrepo was the lead design engineer of the NEES Large High-Performance Outdoor Shake Table located at the Englekirk Structural Engineering Center at the University of California at San Diego and has conducted a number of complex full and large-scale tests on it. Prof.  Restrepo has received a number of awards, including 2006 Chester Paul Siess award by the American Concrete Institute for Excellence in Structural Research, the 2006 Charles C. Zollman award by the Precast/Prestressed Concrete Institute for the best technical paper in the PCI Journal, and the 2008 James Cooper best-paper award at the National Seismic Bridge. Prof. Restrepo also holds an adjunct faculty position at the International School for the Reduction of Seismic Risk at the University of Pavia, Italy.
