An earthquakesimulating shaking table is an effective test platform for seismic simulation research. numerous shaking table facilities exist worldwide today, although most are relatively small, and with limited experimental functions, unable to ensure engineering security or service in the event of an earthquake and unable to simulate the load.
Table 2 reports the average relative density (d r,avg) prior to each shaking event, the number of cycles required to trigger liquefaction (n l), the maximum excess porewater pressure ratio (r u u x σ' vo) measured for each shaking event at each level in the sand profile, as well as the number of cycles required to trigger liquefaction (or.

This shaking table is specially designed for simulating earthquake ground motions of the same intensity as those ones recorded during the northridge earthquake of janu or kobe earthquake of janu. the good performance of seismically isolated structures during this earthquake have persuaded structural engineers, isolator.
Geotechnical earthquake engineering, including 1g shaking table tests, centrifuge tests, field simulation, numerical simulations, instrumentation of selected full scale earth structures, foundation elements and special soilfoundationstructure systems, and.
Ground shaking close to the causative fault of an earthquake is more intense than it was previously believed to be. this raises the possibility that large numbers of buildings and other structures are not sufficiently resistant for the intense levels of shaking that can occur close to the fault.
I want to gratefully acknowledge the contribution of john hessler, supervisor of the civil engineering machine shop at stanford. his practical guidance and outstanding machining work were a great contribution to my efforts. i especially want to thank mr. hessler for his keen insights on the performance of the shaking table.

In order to investigate the longitudinal pounding effect of highway bridges with highpiers under strong ground motions, multiple shaking tables tests of a 110 scaled continuous rigid frame and simplysupported girder bridge with highpiers were carried out. the pounding responses of the bridge model under different earthquake excitations including the uniform excitation and the traveling.
In order to test the validity of two postulates regarding reliquefaction mechanisms and to examine the role of gradational characteristics on reliquefaction resistance, 1g shaking table tests were performed using five sands with differing gradation characteristics. the test results demonstrate that the number of cycles required to reliquefy.

The xaxis model of the shaking table can be represented by the transfer function which is expressed by the following equation: where x(s) lx(t) is the laplace transform of the stage position, i m,x (s) is the laplace transform of the applied motor current, and k f,x is the feedforward control gain along the xaxis.. the pdff control used to regulate the stage position along the horizontal.
The prototype of the model is the longxi tunnel which was highly damaged in the wenchuan earthquake. the input wave of the shaking table is part of the east and west vector components of the wolong seismic waves which is widely used in simulating tunnel dynamic response .the original seismic wave lasts for 180 s, and the peak acceleration value is 0.98 g.

Previous results from shakingtable tests of anchored components suggest that the component attachment is an important parameter that determines its dynamic properties. for this study, a nonstructural experimental model was attached via several attachment designs to a concrete slab and tested on a shaking table to evaluate this contribution.
1 introduction. the structural design of steel silos containing granular materials presents a challenging issue. 1, 2 silos differ from many other civil engineering structures in that the weight of the silo structure is significantly lower than the one of the ensiled granular material and, in case of earthquake ground motion, the particlestructure interaction plays an important role in the.
