Estimating Strength of the Williamsburg Bridge Suspension Cables

Abstract The Williamsburg Bridge, a major east-west route over the East River in New York City, is now being rehabilitated. Before the decision to rehabilitate, the New York City Department of Transportation hired the consulting firm of Steinman, Boynton, Gronquist, and Birdsall to estimate the strength of the bridge's suspension cables. As a result of this major engineering effort, Steinman concluded that the cables have adequate strength. Steinman's analysis and results are compared to results obtained using the Weibull distribution and order statistics to estimate cable strength from wire strength.
