Fatigue Life Estimation of Anchor Plate Structure of Cable-stayed Bridge Based on Hot Spot Stress

The finite element method is adopted to analyze the static loading behaviors of anchor plate structure of Xiazhang cable-stayed bridge,and the hot spot stress method is applied to estimate the fatigue life of the anchor plate structure.The analysis results coincide with the experiment results acquired by Full-scale model test,which shows that the building model is effective and the hot spot stress method is an effective method for the analysis of the fatigue strength of bridge steel structure.
