Description

Probabilistic Fatigue Life Prediction and Risk Assessment of Aging Bridges in Cold Regions Probabilistic Fatigue Life Prediction and Risk Assessment of Aging Bridges in Cold Regions Statement of Work at ASU Objectives The overall goal of the proposed project is to develop, validate and demonstrate a general damage growth and risk assessment methodology for aging bridges in cold regions. Five major objectives are identified: (1) Develop a general life prediction methodology for aging bridges considering small crack growth behavior and multiaxial cyclic load; (2) Develop a general methodology to include corrosion effect on the probabilistic life prediction of aging bridges in cold regions; (3) Develop a general random process representation of fatigue damage accumulation using Karhunen-Loeve expansion technique; (4) Develop and implement a methodology for multi-scale (material, component, and structure) reliability evaluation using both analytical and numerical simulation technique; (5) Develop a systematically integrated educational plan based on the proposed research activities and outcomes to improve both undergraduate and graduate curriculums at Clarkson University.
