Scientists from Arizonta State University (ASU) have found new data concerning the intergranular stress-corrosion cracking (SCC) of metals.

The San Francisco-Oakland Bay Bridge was completed in 2013, took 12 years to build and cost $6.4 billion. It is the largest and most ambitious public works project in California history, in large part because it is designed to withstand a massive earthquake. Since shortly before its completion, however, the bridge has been plagued with questions about its sturdiness.

Last week Caltrans revealed that 120 of the 400 galvanized steel rods that anchor the bridges tower to its foundation are in leaky sleeves flooded with saltwater.   This presents a key vulnerability in the event of a large earthquake.
