testing by the shaking table which is recognized, facility beyond its intrinsic limits, an important instrument to study the dynamic response of a structure. The experimental investigations treated in the paper is also aimed at evaluating the possible effectiveness of some devices for mitigating the dynamic response for the considered
tunnel in northeast China as a background, a shaking table test with a geometric scaling ratio of 1:30 was built. Details of test setup and procedures are introduced first and then the test results are presented. The discussion of the results is based on the peak ground acceleration (PGA), the longitudinal, the contact stress, and the safety factor
To investigate its seismic performance, a shaking table test with a 1/30 scale model is carried out in Structural Laboratory in Wuhan University of Technology. The dynamic characteristics and the responses of the model subject to different seismic intensities are investigated via the analyzing of shaking table test data and the observed cracking pattern of the scaled model
The shaking table tests were conducted in the State Key Laboratory for Disaster Reduction in Civil Engineering at Tongji University. The shaking table used in this test has a table dimension of 4 m by 4 m, and the maximum payload is 250 kN
shaking table tests on bridge structures and bridge piers, information is rather scarce and just a few results are found in literature. The tests performed at LNEC (Carvalho et al, 1978), at the University of California (Williams and Godden, 1976) and at ISMES facilities (Casirati et al, 1996) are among the few papers published on the subject
Sep 01, 2019 The first large-scale shaking table test of fully prefabricated subway station structure in China. Adopting a new type of high precision non-contact laser displacement measuring system in shaking table test. A new fiber grating surface mount strain measurement system is
Jan 01, 2013 A shaking table test of a steel frame with autoclaved lightweight concrete (ALC) external wall panels is described in this paper. The specimen is a two-story full-scale model filled with external vertical wall panels, external horizontal wall panels and internal vertical wall panels
Aug 14, 2021 However, if results are available for an undrained test, then the test itself may be modeled, and the material constants deduced by comparing the numerical results with the experimental observations. Some adjustment will be necessary before a match is found. In the following example, a “shaking table” is modeled with FLAC3D
Dec 01, 2020 Taking a bedding rock slope with weak structural plane as the prototype, a shaking table test with a similarity ratio of 1:10 is designed and carried out. By analyzing the acceleration and displacement responses at different positions of the slope, the seismic response and instability mechanism of rock bedding slope under different seismic amplitudes, frequencies, and durations are
Shaking table tests are described of a segmented arch rib model designed of this material to simulate the monolith joint opening behavior of an.arch dam. Also, the test of a model of Koyna Dam is mentioned, where the model behavior simulated reservoir cavitation
Aug 01, 2021 Shaking table test on ultra-large diameter tunnel passing through soft-hard stratum. • A modified similitude-ratio design method is proposed, with the soil-structure relative stiffness as the main control factor. • The comparison between test and numerical results shows a good agreement. •

Jul 23, 2018 Shaking table test on vibration control effects of a monopile offshore wind turbine with a tuned mass damper. Bin Zhao, State Key Laboratory of Disaster Reduction in Civil Engineering, Tongji University, Shanghai, 200092 China
Supporting the shaking table and test payload mass with air pressure, allows the hydraulic system to be more efficient in subjecting the system to dynamic loading. The horizontal gap between the edge of the shaking table and the interior foundation wall is sealed by a wide vinyl strip providing the hermetic seal required to float the table with
Shaking Table Test on a Nonductile Concrete Frame. We completed Shaking Table tests on a nonductile concrete frame this past Thursday, February 16, 2006. The structure is a three-bay by three-story plane frame. Half the frame has pre-1976 UBC ordinary details and the other half has ductile details - the odd mix is to slow down the collapse so

Feb 05, 2021 A shaking table test of the isolated model was conducted and the aspect ratio was found to have a great influence on the structural rocking response. The response of the large aspect ratio (LAR) model was larger than that of a model with a small aspect ratio. The bearings in the LAR model were more likely to be tensioned
