Berkeley quake trial shows bridge safety ideas
05/27/10 San Francisco Chronicle — A mock-up bridge and a mock-up rail car shook, rattled, but never rolled as earthquake engineers from UC Berkeley demonstrated a system designed to keep bridge traffic moving even in the strongest of seismic shaking. The 30-foot, scale-model bridge, designed and built by researchers at the university's Pacific Earthquake Engineering Research Center, was erected on a huge "shake table" that created the same violent ground motions that have marked major quakes in California, Japan and Chile.
