中文摘要: 根据目前报道的实验研究成果,本文介绍了钢框架梁柱节点低周疲劳损伤积累的分析方法。结合研究者提出的分析模型和设计规范,综述了梁柱节点寿命评估方法和低周疲劳损伤积累评估模型。重点包括S-N曲线、断裂力学和局部应变分析方法的比较,并对进一步的应用进行了探讨。最后为在国内进一步开展相关研究工作提出了建议。
Abstract:Based on the current experimental studies, low-cycle fatigue damage accumulation assessment approaches of steel beam-to-column joint are presented. As a study of the current analytical models and design codes, investigations in the area of low-cycle fatigue life prediction and damage model are outlined. This includes the comparative studies of S-N line approach, fracture mechanics approach & local strain approach. Further application and development of these models are discussed. Finally, suggestions are given for further research work.
