Installing NEES Web Services 2.0

27 Jul 2010 | Contributor(s): Rajesh Thyagarajan

The NEES Web Services 2.0 is a Java based web application that can be deployed into any servlet container such as Tomcat and Jetty. The source code and the binary code are both shipped as a part of the package. However, we have only tested the deployment under the Tomcat 6 or later version. This...

iSeismograph System Guide

27 Jul 2010 | Contributor(s): Rajesh Thyagarajan

iSeismograph is a telepresence-demonstration and educational tool built on top of RDV and Data Turbine. It takes advantage of the in-board video-camera and 3-axis accelerometer built into all new Apple MacBook products to provide an telepresence demonstration often referred to as "Data Turbine in...

UCD/CGMDR-05/03 Collaborative Research: Dynamic Behavior of Slickensided Surfaces - Centrifuge Data Report for CLM01

05 Jun 2010 | Publications | Contributor(s): Christopher Meehan, James Duncan, Ross Boulanger

This document describes a centrifuge test that was performed using the UC Davis geotechnical centrifuge. The purpose of this test was to measure the amount of displacement that occurs during earthquake shaking along a preformed slickensided clay surface. The recorded data can be used to evaluate...

Development of a Direct Test Method for Dynamically Assessing the Liquefaction Resistance of Soils In Situ

05 Jun 2010 | Publications | Contributor(s): Brady Cox

This dissertation details work conducted by researchers from the University of Texas at Austin aimed toward the development and implementation of a new in-situ liquefaction testing technique. This technique is an active method that may be used to directly evaluate the liquefaction resistance of...

Experimental Investigation of a Full-scale Flat-plate Reinforced Concrete Structure Subjected to Cyclic Lateral Loading in the Inelastic Range of Response

05 Jun 2010 | Publications | Contributor(s): Damon Fick

Reinforced concrete flat-plate construction is a popular building type because of the simple formwork required for construction and the clearance that is provided for mechanical and electrical equipment. During the period 1950 through 1980, buildings using the flat-plate for the lateral-force...

Performance of T-shaped Reinforced Concrete Structural Walls under Multi-Directional Loading

26 May 2010 | Publications | Contributor(s): Beth Brueggen

The study described in this thesis was a key component of a larger, collaborative project involving researchers from the University of Minnesota (Narina Jung, Ben Johnson), Iowa State University (Sri Sritharan, Jon Waugh, Sriram Aaleti), University of Puerto Rico at Mayaguez (Ricardo Lopez) and a...

Anchorage Detailing Effects on Lateral Deformation Components of R/C Shear Walls

26 May 2010 | Publications | Contributor(s): Benton Johnson

Structural walls, or shear walls, are elements used to resist lateral loads, such as those generated by wind and earthquakes. Structural walls are considerably deeper than typical beams or columns. This attribute gives structural walls considerable in-plane stiffness which makes structural walls...

Baja quake sheds light on liquefaction

25 May 2010 | Notes | Contributor(s): Mary Caperton Morton

Data collected by a unique array of instruments located near the epicenter of the magnitude-7.2 earthquake that struck Baja California April 4 are providing scientists with new insight into the phenomenon of liquefaction, a potentially dangerous side effect of major earthquakes.

110-Foot Concrete Bridge Withstands 8.0 Earthquake Simulation

25 May 2010 | Notes | Contributor(s): Rajesh Thyagarajan

After a succession of eight separate earthquake simulations, a 110-foot long, 200-ton concrete bridge model at the University of Nevada, Reno withstood a powerful jolting, three times the acceleration of the disastrous 1994 magnitude 6.9 Northridge, Calif. earthquake, and survived in good condition.

Oregon may Build Nation's First Tsunami Evacuation Structure

25 May 2010 | Notes | Contributor(s): Dan Cox

Residents of a small Oregon coastal community are moving closer to the creation of something that's never before been built in the United States - a structure designed specifically to withstand a major earthquake and the force of a tsunami, and give people somewhere to run to for safety.

LAX Theme Building shakes as UCLA engineers test for quakes

07 May 2010 | Notes | Contributor(s): Rajesh Thyagarajan

The Theme Building in the middle of Los Angeles International Airport shook for a few moments Tuesday as engineers tested the space-age structure’s earthquake readiness.As his earthquake simulator - or "shaker" - revved up, UCLA professor of earthquake engineering Bob Nigbor stood on the...

Researchers test LAX's Theme Building for quake stability

07 May 2010 | Notes | Contributor(s): Rajesh Thyagarajan

The earth literally moved - albeit gently - for 10 minutes on Tuesday when scholars and engineers tested the durability of the iconic Theme Building at Los Angeles International Airport, which is set to reopen next month.A portable shaking machine nicknamed "Mighty Mouse" was mounted on the Theme...
