摘要
研究了地板梁上的表面蚀坑尺寸不同时剩余静强度安全系数的变化规律;基于ABAQUS建立了地板梁有限元模型,分析在蚀坑尺寸不同时应力集中系数的变化规律及蚀坑位置对剩余静强度安全系数的影响规律。为地板梁腐蚀损伤修理提供理论依据。
The change rule of residual static strength safety coefficient when the pitting sizes on the floor beam were different was studied.The finite element model of floor beam was established based on ABAQUS.The model was used to analyze the change rule of stress concentration coefficient and the effect of pitting location on residual static strength safety coefficient when the pitting sizes were different in order to provide theoretical foundation for floor beam corrosion damage repair.
