欧洲近海结构用钢研究计划在第一阶段(1975—80年)关于海洋焊接结构在疲劳载荷下工作性能的研究基础上,于1981—87年继续进行了第二阶段的研究工作。参加国家有欧洲经济共同体6国及挪威、加拿大等。本文综合报道第二阶段研究情况与主要成果,内容包括:板厚对疲劳强度的影响,焊后改进技术与腐蚀疲劳,疲劳载荷及变幅疲劳试验,疲劳分析的断裂力学方法,某些管节点的应力分析等;并对研究计划的背景及今后研究工作的方向作了介绍。
In the first phase (1975-80) of the European offshore structural steel research project, based on the study of the working performance of marine welded structures under fatigue loading, the second phase of research work was continued in 1981-87. The participating countries are the European Economic Community 6 countries, Norway and Canada. This article comprehensively reports the second phase of the research situation and the main results, including: the effect of plate thickness on fatigue strength, post-weld improvement technology and corrosion fatigue, fatigue loading and variable amplitude fatigue testing, fatigue analysis of fracture mechanics methods, some tube nodes The stress analysis, etc.; and introduced the background of the research plan and the direction of future research work.
