Quantitative failure metric for gravity dams.

- Abstract
Quantitative failure monitoring is a critical tool for safety assessment of concrete dams. This includes damage occurrence, intensity, location, number, size, and propagation pattern. Such an assessment is essential for a quantifiable prioritization of repair and will thus reduce overall cost and improve safety. This paper will address this timely topic through the nonlinear transient analysis of a dam and failure will be ascertained through a multi-scale damage index. A damage-plastic model for mass concrete is used, Drucker-Prager elasto-plastic one for the foundation, and infinite elements are used for far-field boundaries. Water-dam interaction is accounted for through fluid finite elements. It is determined that the proposed damage indices can indeed provide a quantitative metric for the degree of failure in gravity dams in terms of the input dynamic motion.
