Fatigue safe control assessment method on steel crane structures in service is put forward based on fatigue dynamic reliability . after investigating and summarizing many engineering usage and appraisal . based on the miner accumulation damage model , in a fatigue reliability point of view , the remain fatigue life assessment equation in the ( technical specification for inspection , assessment and strengthening of steel structures ) ) ( yb9257 - 96 ) is analyzed , and the probabilistic meanings of the additional safe factor is proposed 4 、在上述工作的基础上,基于疲劳动态可靠性,提出了钢结构吊车梁疲劳安全控制评定方法;从miner累积损伤的定义出发,提出了在役钢结构吊车梁疲劳剩余寿命评估的可靠寿命评估方法,与现行《钢结构检测评定与加固技术规程》 ( yb9257 - 96 )中的安全期限寿命评估方法进行了分析比较,解释了安全期限寿命评估方法的概率意义,通过算例说明了本文提出的可靠寿命评估方法的合理性。
