摘要 为避免锈蚀造成的钢结构的缺陷与损伤对建筑剩余寿命的重大影响,对既有钢结构锈蚀损伤的分布规律进行了研究。结合某服役20年大跨度空间管桁架结构的锈蚀情况,分析了既有大跨度钢桁架结构的锈蚀损伤分布,为掌握既有钢结构建筑锈蚀损伤的发展、分布规律提供了参考。 To avoid the significant impact of defects and damage of steel structure caused by corrosion on the remaining life of buildings,the distribution law of corrosion damage of existing steel structure is studied.Combined with the corrosion of a large span space pipe truss structure in service for 20 years,the corrosion damage distribution of the existing large span steel truss structure is analyzed,which provides a reference for mastering the development and distribution law of corrosion damage of existing steel structure buildings.
