square-shaped geocell reinforced soil retaining wall has a substantially high seismic stability against a large seismic load, two shaking table model tests on reinforced soil retaining walls by using square-shaped geocell models and geogrid models backfilled in sandy soil were carried out. And a gravity-type retaining wall model was also tested for
SHAKING TABLE TESTS OF SQUARE-SHAPED GEOCELL REINFORCED SOIL RETAINING WALLS WITH DIFFERENT BACKFILL COMPACTION DEGREES Christian HAUSSNER1, Takashi KIYOTA2, Zelong Xu3, Toshihiko KATAGIRI4 ABSTRACT In order to investigate the influence of the backfill compaction degree on
vibrations induced from the shake table before each model test. The computed shear wave velocity of sand ranged from looms to 150 ms before and after shaking. The shaking table tests were conducted in March 1999. Tests of following five group model cases had been performed 1 Free-field tests Case 1.
The model design of shaking table test is the first step of the test, which directly determines the results of the seismic tests objective, and is important to the success of the seismic test 2. Since a shaking table test model design on a FPB isolated building is significant, this paper aims to solve the core issues of shaking table test
Jan 01, 2010 Table 1 shows a summary of previously conducted laboratory experiments available to the authors relevant to the earthquake-induced settlement of clean sands. It can be seen that these settlement studies are based on test results for both dry and saturated sands. It was found that the volumetric strain v of dry sand due to earthquake shaking depends on

The shake table test model is designed based on the similitude law with a 140 scale. The dynamic characteristics, cracking pattern, failure mechanism, as well as maximum acceleration and deformation response are investigated. The corresponding finite-element analysis shows a good agreement with experimental results. It is concluded that this ...
Oct 01, 2015 The multi-function shaking table system is composed of two main tables with 700 kN payload each, two other tables with 300 kN payload each, and a 70-m long test trench, as shown in Fig. 2. All four tables are moveable along three-degrees-of freedom transversal, longitudinal and rotational in the test trench and work as a large linear shake ...
In this paper, in order to investigate the seismic stability of the new-type of geocell reinforced retaining, a series of pullout test and shaking table model tests was carried out by using the new-type geocell and geogrids as a tensile-reinforcement in the sandy and gravelly backfills. Furthermore, an unreinforced retaining wall T-shape ...
For this purpose, a shaking table test and its numerical analysis as well as structural damage identification were also conducted. This paper focuses on the investigation of the seismic behavior of Shimao Building. Firstly, the results of a shaking table test on the 130 scale building model will be presented.
May 01, 2018 Based on the shaking table size and the allowable taking weight of shaking table facility, the scaling factor for geometry size was determined as 18 i.e., S l N 1 8.The scaling factor of soil density was fixed as 1.0 to make the prototype soil applicable in shaking table test, which subsequently resulted in a low effective stress in model test.
2 Test 2 was a shaking table test of a flexible immersed tunnel in a saturated sand site under horizontal earthquake input, which shared the same site fabrication and tunnel model with test 1. In order to fully saturate the sand, a water pipe was embedded in the inner side of the model box in the process of compacting soil, of which the water ...
May 25, 2020 Parameters investigated include the width of geocell, depth of placement of geocell below the footing, depth of embedment of footing, infill materials, and the dynamic force level of the excitation. The effect of aforesaid parameters was studied by performing field vibration tests over the reinforced test beds of 3.6 m 3.6 m 1.2 m.
They were input in two directions during the shaking table test, and the peak accelerations of each seismic wave were adjusted to 0.40g and 0.60g. The model test was conducted first on the mid-story isolation model and then the anti-seismic mode. A total of 16 test conditions were carried out in this experiment.

3.15 Test Response Spectrum TRS The acceleration response spectrum that is developed from the actual time history of the motion of the shake table test as measured by reference control accelerometers mounted on the shake table at a location near the base of the UUT. 3.16 Transmissibility The nondimensional ratio of the
Shake table tests provide a true representation of seismic phenomena including a fully dynamic environment with base excitation of the test structure. For this rea-son shake tables have become a staple in many earthquake engineering laboratories. While shake tables are widely used for research and commercial applications, further
