Gauging the Seismic Safety of Retaining Walls

Researchers at the UC San Diego Jacobs School of Engineering are testing a full-scale, 7-meter-tall retaining structure on the world's largest outdoor shake table in March and April. The tests at the Englekirk Structural Engineering Center at UC San Diego, conducted on a scale never achieved before, will collect high-quality data on the overall seismic response of the structures, which are an integral and ever-growing component of our nation's infrastructure.

The data will be used to enhance the design guidelines for mechanically stabilized earth walls in the areas where earthquakes are most likely to happen. It will also help validate previous research and existing numerical models.

The tests, led by structural engineering professors Patrick Fox and Ahmed Elgamal and Ph.D. student Andrew Sander, are sponsored by the NSF's George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES).

  1. I'm planning to buy this one and use it for creating computer programs and in making engineering drawings.. won't these softwares make the netbook's performance slower?.
