NEESCollapse project objectives are: to document a comprehensive collapse experiment with data that covers the range of response of a 4 – story steel frame structure from elastic behavior to incipient collapse, to evaluate effectiveness of analytical models that model explicitly deterioration and to generate landmark experimental data to be used by all project participants

The NEESPiles project will involve the laminar box filled with saturated sand at a relative density of 40-50%. The first test denoted by LG-1 involves a level ground deposit subjected to shaking, and the second experiment denoted by SG-1 involves a gently sloping ground at a slope of about 2 to 3 degrees.
Since the start of the NEESWood Project on September 15, 2005, preparations are underway for the NEESWood Benchmark shake table testing of a two-story
woodframe townhouse that will require the simultaneous use of the two three-dimensional shake tables acting in unison at the SUNY-Buffalo NEES node. As the largest full-scale three-dimensional shake table test ever performed in the U.S., the results of this series of shake table tests will serve as a benchmark for woodframe performance as well as for the validation of numerical models. The first testing phase is planned for the first week of June 2006.
On the week of March 27-31, 2006 Seismic Qualification of Potential Transformers was conducted on one of the two new seismic simulators
of the Structural Engineering and Earthquake Simulation
Laboratory (SEESL) of the Department of Civil, Structural and Environmental
Engineering (CSEE) at the University at Buffalo (State University of New York).
The study is sponsored by MCEER (Multidisciplinary Center for Earthquake Engineering Research), by EPRI (Electric Power Research Institute) and by EUC (Electrical Utility Consortium). For More information, please click here. NOTE: This section is password protected!

Zipper Frames Test 2005
Dynamic Seismic Response of Steel Braced Frames with Innovative Bracing Configurations
On Tuesday August 2, 2005 we conducted, 2nd phase shake table testing
of a 3-story, 42 kips, steel frame model equipped with advanced braces ("Zipper Frames")
on one of the two new seismic simulators of the new NEES expansion of the Structural
Engineering and Earthquake Simulation Laboratory (SEESL) of the Department of Civil,
Structural and Environmental Engineering (CSEE) at the University at Buffalo
(State University of New York). The testing was similar to the test in phase 1 (see bellow) with the beams of the frame restrained laterally in their mid-span to prevent torsion. This Experiment was webcasted Live. The test lasted whole day and the specific starting times of different test components were posted as the test progresses. To see the experiment click here.

On Friday December 3, 2004 we conducted a demonstration test of a 6-story, 240 kN
seismically isolated model on one of the two new seismic simulators of the
Structural Engineering and Earthquake Simulation Laboratory (SEESL) of the
Department of Civil, Structural and Environmental Engineering (CSEE) at the
University at Buffalo, State University of New York.
On Friday, September 24, 2004 we conducted an opening ceremonies test.
The demonstration featured a scale model of a five-story building, located on one shake table.
The model was equipped with seismic dampers in the east-west direction.
