RISFracture Mechanics-Based and Continuum Damage Modeling Approach for Prediction of Crack Initiation and Propagation in Integral Abutment Bridges
Publisher: American Society of Civil Engineers
Abstract: Piles in integral abutment bridges (IABs) are prone to fatigue damage crack attributable to cyclic load caused by daily and seasonal temperature variations. Previous research has shown that the fatigue life of these piles ...
