摘要
采用有限元法对厦漳跨海大桥锚拉板结构进行静载分析,并用热点应力法对其进行疲劳寿命评估,计算结果与足尺模型的静载和疲劳试验结果吻合良好,表明所建模型正确,同时也表明热点应力法不失为一种校核桥梁钢结构疲劳强度的可行方法。
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.
