...H. Kyokawa; Y. Yamazaki; J. Koseki; T. Konami; T. Nishi; T. Kubota This study is aimed at improving the seismic stability of bridge abutments. To study the effects of the combined use of a block of expanded polystyrene (EPS) and geogrid, a series of 1 g shaking table tests were conducted...

...-g shaking table tests is conducted to assess the dynamic properties of the sand-EPS beads mixtures with a particular focus on the stress-strain response and the variation of shear modulus and damping ratio at the range of medium to large levels of strain. The influence of various parameters...

...-static methods. However, the influence that the choice of wall facing could have on reinforcement connection loads is not adequately addressed in the current pseudo-static methods of analysis. In this study, two shaking table tests were carried out on full-height panel and modular block reinforced soil...

... (representing two, three and four storey structures) were tested with and without the addition of geomembrane/geotextile interface using the shaking table test setup by employing harmonic and modified/scaled ground motions. Experimental results showed that the geomembrane/geotextile interface significantly...

... and geogrid for a quay-wall, which is referred to simply as an ‘SG-WALL'. The seismic performance of the SG-WALL structure was investigated through a series of shaking-table tests. The test results showed that the SG-WALL structure has a high seismic resistance. A numerical simulation of the shaking-table...

...S. Zarnani; R. J. Bathurst The paper reports the results of six shaking table tests using reduced-scale model walls constructed with expanded polystyrene (EPS) panels to reduce dynamic earth loads due to base shaking. The results are compared with a nominal identical rigid (control) wall...

...M. M. El-Emam; R. J. Bathurst The behavior of six reduced-scale reinforced soil walls under base excitation is investigated using physical shaking table tests. The models were tested to isolate the influence of facing geometry, facing mass and facing toe condition on response to simulated seismic...

...J. Koseki; Y. Munaf; T. Sato; F. Tatsuoka; M. Tateyama; K. Kojima A series of shaking table tests was performed on relatively small-scale models of a geosynthetic-reinforced soil retaining wall with a full-height rigid facing and conventional type (gravity-type, leaning-type, and cantilever-type...

..., formed through various combinations of three geosynthetics (a geotextile, a smooth geomembrane, and a geonet). The dynamic frictional properties were estimated using cyclic direct shear tests, shaking table tests conducted at a normal g-level of 1g as well as at high g-levels, and on a 100 g-ton...

... facings were conducted using a shaking table and a centrifuge. The effects of soil density, geosynthetic length and strength on the magnitude of horizontal wall displacements were investigated experimentally. An empirical relationship to estimate horizontal wall displacements is proposed. Light-weight...
