    Sep 10, 1997 Publication Date:September 10, 1997. During the past decade, earthquakes in California and Kobe, Japan have caused the dramatic collapse of freeways, bridges and other structures built according to stringent earthquake-resistant design codes. Theoretical simulations and scale models have only limited usefulness in predicting structural damage, so MIT researchers and their collaborators have prepared a conceptual design for a 30-by-30-meter shake table
