CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The primary focus of a structural shake table system is the accurate reproduction of acceleration records for testing. However, many systems deliver variable and less than optimal performance, particularly when reproducing large near-field seismic events that require extreme table performance.Shake Table Tests on Infill Plasterboard Partitions ... The tested plasterboard partitions exhibit a good seismic behaviour, both in their own plane and out-of-plane, showing light damage up to 0 ...

Parkfield Earthquake Shake Table Exhibit

The shake table exhibit envisioned promoting earthquake awareness and preparedness for Californians by merging earthquake science and art in an innovative, interactive display. It was a collaboration between USGS seismologist Andy Michael and Australian artist, D.V. Rogers.Tables. Turn the tables with a variety of styles meant for multiple purposes. Whether you’re accenting an empty space or require a functional table for the sitting or living area, there are an array of appealing options that turn any space into a useful perch for a cup of coffee, vase, or lamp.

Shake Table Test

Abstract: This paper is concerned with investigation of the dynamic behaviors of cranes under seismic effects. For this purpose, firstly we have performed experiment on a 1/20 scale crane model on the shake table with real earthquake data, then a multi degree-of-freedom non-linear mathematical model is developed including behavior of the container cranes under earthquakes and simulated.Shake Table. This shake table exhibit allows users to explore the effects of vibration on physical structures. By changing the frequency of vibration, users are able to find harmonic frequencies within their own structures and explore options to increase a structure's ability to withstand vibration.

Shake Table Project Is The Big One | ASCE

Aug—A research team at the University of Nevada, Reno (UNR) is designing a massive shake table and soil box that will be one of the largest in the world when it is completed in two years, and the only one of its size that can shake soil in two directions simultaneously.Both shake table tests and numerical analyses presented in this study illustrate that the use of USRBs is a more effective, reliable, and robust alternative that can significantly reduce the span unseating damage caused by the uncontrollable sliding of ULNRs. 2.
