Probabilistic Fatigue Life Prediction and Risk Assessment of Aging Bridges in Cold Regions

Project: Research project

Project Details

Description

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.
