摘要
针对焊接钢结构的特点，指出了传统疲劳寿命估算方法中的缺点，并运用断裂力学的理论总结出估算焊接钢结构疲劳寿命的计算步骤，以实例说明该方法的优越性和可操作性。
In view of the characteristics of welded steel structure,this paper indicates the disadvantages of traditional methods for estimating its fatigue life,and concludes the calculation procedures with new fracture mechanics method as well as the benifits and feasibility which are illustrated by an example
