Oct 26, 2016018332Accelerometers are of analog voltage output type with a full-scale acceleration range of 1772 g along both the x and y axes, with sensitivity of 0.001 g and these accelerometers were connected to the shaking table controller through a junction box for data acquisition . Non-contact type ultrasonic displacement transducers were used to measure ...
excitation used in the shaking table test is 1940 El Centro NS component. The time scale is not changed but the input amplitude I.A. is selected at a wide range of intensities. Figure 2 shows pseudo velocity spectrum based on the acceleration measured on the shaking table. The measured structural response quantities were all horizontal floor
Apr 16, 2020018332The available data include acceleration measures, relative displacements between the structure and a stiff steel frame placed inside the structure that moved with the shaking table, and the displacements measured through an optical system of grid markers in the south, east, and north fa231ades.
The shaking table at the Geotechnical Engineering Laboratory, University of Tokyo, is 2 m wide and 3 m long, and is capable of applying bi-directional horizontal accelerations. The bearing capacity of the shaking table is 7 tons, and the maximum applied acceleration

The EMSS designed by Dr. Chaniotakis and his coworkers can hold a 10-story building weighing 1,000 tons. It can operate for 30 seconds and achieve an acceleration of 1 g, a velocity of 3 meters per second and a displacement of half a meter. Each of its nine panels can shift up and down and sideways, rock front to back and side to side, and twist.
Figure 2. One accelerometer was located on top of the shake table. Four others were located on the turbine tower, one at the base, one at the lower joint, one at the upper joint, and one on at the top of the nacelle. Excitation used for the tests was derived from the East-West component 0.15 g peak ground acceleration of the
usually the models are prepared at reduced scale given the size of full civil engineering structures. The preparation of models at reduced scale, using laws of similitude, is difcult, but examples of shaking table tests on large structures are given in 6, 7.

shaking table to be used caused the total mass in this model to be half the weight required for the true replica model in the similitude law. Therefore the applied peak ground acceleration PGA was twice the PGA required for the true replica model due to the reduction of artificial weight as shown in Table 1 Hosoya et al. 1995.
The present paper deals with two shaking table tests performed at the University of Bristols EERC laboratory. The tests were performed on a physical model consisting of a Leighton Buzzard sand deposit and a one-storey steel model structure. Some of the test results are presented and discussed in terms of acceleration and displacement responses.
Tu et al. 14 conducted shaking table tests on four full-scale single-story structures to investigate the out-of-plane behaviour of unreinforced masonry panels in RC frames. Hanazato et al. 15 presented shaking table tests using full-scale model of the timber framed brick masonry walls. Furthermore, based on adequate scaling laws, scaled ...
