New apparatus was designed and developed to model simultaneous faulting and shaking on buried instrumented pipelines. The experimental apparatus consisted of a 2 m by 2 m wide and 0.6 m deep tank, which was fixed to the 2 m by 3 m shaking table at the Geotechnical Engineering Laboratory, University of Tokyo. The experimental tank …

A shaking table model test was carried out to study the failure process and dynamic response of the cross tunnel with ultra-small spacing under seismic motions with various types and peak accelerations. The results show that the seismic damage of the cross tunnel model has significant failure stages.

Thus, this study seeks to assess the dynamic response of seven-story concrete frame type buildings without a basement, one basement story, and two basement stories, considering fixed and flexible bases. For this purpose, the experimental tests on the small shaking table were executed with a small scaling coefficient of 1:50.
The small-scale shaking table test results had a close agreement with the finite element analysis results of full-scale free-form structures under the scaled El Centro earthquake. With this investigation, the small-scale shaking table tests were sufficiently validated to study the seismic behavior of full-scale free-form structures. (3)
This research comprises a series of shaking table tests and finite element analyses of scaled soil-foundation model to determine the dynamic interaction effects between the foundation and the underlying soil.

Three experimental structural models of a small radius curved bridge, which include a three-span small radius curved bridge model and its corresponding two different simplified models that are widely used (e.g., one mass simplified model and one single pier simplified model), will be constructed, and then three bridge structure–foundation soil …
As the limit of size and bearing capacity of centrifuge shaking tables is much smaller than that of traditional shaking tables, centrifuge test models are usually built on a small scale. It is impossible to adopt reinforcement and concrete materials to manufacture small-scale models to simulate the reinforced concrete prototype.
