... 9 1.1 Background Structural redundancy is defined as the ability of a structural system to continue to carry load after the failure of one or several structural components. Although this concept is well understood, no consensus is currently available on nonsubjective measures engineers should use to quantify structural redundancy and how to apply such measures to design adequately redundant bridges.
