1997-9-10 · 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" that can subject a full-scale building or other structure to the forces of a real earthquake.
2020-10-13 · amount of empirical data through scale model shake table testing. A suite of earthquake times histories are considered in evaluating a 10. th. scale soil-structure model using a flexible wall barrel on a 1-D shake table. San Francisco Young Bay Mud (YBM) is used as the prototype soil and a 3-5 story narrow building the prototype structure.
