2007 BLIND ANALYSIS CONTEST BY E-DEFENSE
The executive committee of the E-Defense steel building project, sponsored by the National Research Institute for earth Science and Disaster Prevention in Japan, has announced the 2007 Blind Analysis Contest for a full-scale four-story steel building, which will be tested to collapse on the world's largest three-dimensional shaking table located at Miki City, Hyogo Prefecture, Japan. The test will be conducted from September 20 to 30, 2007, by applying a scaled version of near-fault motion recorded during the 1995 Kobe earthquake.
The contest will be carried out by two working groups (WGs) under the executive committee. The "Analysis Method and Verification WG" is responsible for announcement, distribution of data, answering questions, and determination of contest winners. The "Building Collapse Simulation WG" will produce the experimental data for the collapse of the four-story building.
Each participant should predict the responses before and after the test, and the closest predictions to the test results will win the awards. Because the actual loadings will be determined during the course of the testing based on observed response, the contest has two parts: pre-test analysis based on anticipated earthquake loadings, and post-test analysis using the actual loadings. The building analytical model for the post-test analysis must be identical to that for the pre-test analysis.
Analysis methods are categorized as either 2D or 3D. Each category will have two winners: one from researchers including students, and another from practicing engineers, for a total of four winners.
While names and affiliations of all participating teams will be identified, results will be presented anonymously (unlabeled) except for those of the winners.
Winners will be invited to and honored at a special session of the 14th World Conference on Earthquake Engineering (14WCEE) in 2008 in Beijing, China, with their travel expenses and accommodations covered by the contest sponsor.
