浮式平台上部模块非管节点SCF控制方法

应力集中系数（Stress Concentration Factor，SCF）是评估节点疲劳损伤的重要参数。针对浮式平台上部模块非管节点的SCF控制，设计5种加强形式，采用Ansys软件对非管节点进行SCF分析。结果表明：筋板加强可有效改善面外弯矩作用下的应力集中；扣管加强对轴向力、面内弯矩和面外弯矩均具有较好的改善效果。

SCF Control Method for Non-Tubular Joint of Upper Module of Floating Platform

Stress Concentration Factor (SCF) is an important parameter for evaluating the fatigue damage of joints. In view of the SCF control of non-tubular joint of upper module of floating platform, five reinforcement forms are designed, and the SCF analysis of non-tubular joint is made with Ansys software. The results show that: the stiffened plate reinforcement can effectively improve the stress concentration under the action of the out-of-plane bending moment; the buckle tube reinforcement is of better improving effect on the axial force, in-plane bending moment, and out-of-plane bending moment.
