A series of shaking table tests on a scaled model were conducted to investigate the effect of steel braces on reinforced concrete frame structure across earth fissure under earthquake. In the test, a 1/15 scaled model structure taking into account soil–structure interaction was designed on the basis of similarity theorem.
May 26, 2015 was placed on each floor. Hence, the total weight of the prototype over the shaking table, including the RC beam, is about 251.14 kN. The masonry walls were constructed with calcareous tuff stones and lime-cement mortar with weight ratios of the components of 10.5 (sand), 11 (lime) to 1 (cement). The masonry units have an
g is the wall axial load; Ve and Me are the shear force and bending moment obtained from the elastic analysis, respectively. The inplane aspect ratio height- -to-length (h/L=1/) of the wall has shown its influence in the α shear strength Vm, in several tests performed on walls under cyclic loading and on the shaking table test shown in figure 7.
double street light of load of 50 KN/m. To model the surface load of the decorativestreet light and casted concrete wall, the total load is transferred to the pavement surface through an average contact pressure of 50 KN/m. This work was carried using 50% quarry dust and 10% cement mixed with soil. The base of the structure was used

Jan 01, 2017 2.2. Test Device. The seismic response test of a RC frame structure with EPSC latticed concrete wall was performed by the shaking table at the Institute of Engineering Mechanics, China Earthquake Administration, Harbin, China. The dimension of the shaking table is 5.0 m x 5.0 m in plane.
Feb 13, 2009 SIMULATION OF THE SHAKING TABLE TEST 589 2. DESCRIPTION OF THE R/C SHEAR WALL SPECIMEN 2.1. Geometry and mass distribution The test specimen is a seven-story full-scale R/C shear wall structure (Figure 1) [1–4].The structure was designed with the displacement-based capacity approach for a site in Los Angeles
The L/H ratio ranged from 0.6 – 0.9, and the walls were primarily vertical except for one test inclined at 70o to the horizontal. During testing, facing displacements and accelerations within the backfill were recorded at varying levels of shaking intensity. Mechanisms of deformation, in particular, were of interest in this study.
Dec 02, 2020 The shaking table tests of both cases with and without collisions were performed under the same set of input motions. 2.3 Test procedure The test model of the base‐isolated building was placed on the shaking table, and the retaining wall specimen was installed on the right side of the test model with a clearance gap of approximately 100 mm ...

2.3 Integration of AE monitoring/Shaking Table Test and AE Analysis The sampling rate of DAQ for AE was 800kHz, which was much higher than the DAQ rate for shaking table test (200Hz). So, both readings from AE monitoring and shaking table test could be coupled after the synchronization on the starting time. After test, the AE signal
Jun 03, 2014 Izawa and Kuwano (2011) and Kuwano and Izawa (2011) performed a series of centrifuge tilting table tests and shaking table tests on geogrid walls with facing panels. They discussed a method for evaluating the seismic stability of a geogrid-reinforced soil wall.
Jan 01, 2017 Tu et al.  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.  presented shaking table tests using full-scale model of the timber framed brick masonry walls.
Typical final crack patterns of walls during shaking table tests are shown in Fig. 4. A previous study (Carrillo and Alcocer, 2012a) has determined the effect of each mode of deformation on the total displacement of wall specimens tested under shake table excitations.

In this paper, a 1/5 scale reinforced concrete (RC) frame-wall model of shaking table was conducted to study the dynamic behavior and damage features of reinforced concrete structure under earthquake excitations which can also verify the accuracy of nonlinear seismic response analysis …
The influence of the natural hydraulic lime-based grout on the dynamic behaviour of injected multi-leaf stone masonry elements is discussed in the paper. Shaking table experiments on two stone masonry buildings, tested before and after grout injection, have been performed. The paper focuses on the analysis of both the recorded accelerations and related displacements, at the bottom and at each ...
Jul 14, 2017 A series of shaking table tests were designed and conducted to study the seismic performance of an inverted T-shape cantilever retaining wall with an anti-sliding tooth at the base using EPS composite soil as backfills. For comparison, the same wall model retaining Nanjing fine sand was simultaneously excited. The macro phenomena and seismic behaviors of two wall–soil systems are …

In order to reveal the main factors affecting the deformation of reinforced soil retaining wall and the influence of various factors on the deformation, the constitutive relation is discretized into four aspects of soil, geogrid, wall panel, and contact surface, and discrete element matrices are, respectively, constructed, with the method of separate finite element.
