摘要:
输电线路铁塔结构，由于直接暴露在大气环境中，极易因大气污染物、恶劣环境的作用而受到腐蚀，导致构件有效钢材厚度降低。对于受削弱铁塔构件力学性能的研究，目前尚显不足。本研究结合实际工程，对受到不同程度腐蚀的输电铁塔节点结构，建立有限元模型进行数值模拟计算，得到其刚度、强度的折减率。研究表明在节点锈蚀厚度不超过0.2〖KG3x〗mm、构件锈蚀厚度不超过1〖KG3x〗mm的条件下，输电线路铁塔结构可以继续使用，本研究可为同类实际工程提供参考。
Abstract:
Steel transmission towers, which are exposed to atmosphere, are easily to be corroded. However researches on the mechanical properties caused by corrosion were rarely reported. This paper presents a numerical analysis on strength and stiffness reduction rate of a corroded steel joint in steel transmission towers. The research showed that given the node corrosion thickness is less than 0.2〖KG3x〗mm, the thickness of the corrosion of components is less than 1〖KG3x〗mm, the steel transmission tower structure can be kept for further use. The research provided reference for similar engineering.
